Is OTHER wrong in the post ? POST : This is a long one, so be prepared.  A bit of background..... My wife and I got married pretty young. We both belonged to a very conservative religion where that was normal.  But sexual repression was also a part of the religion, and thus we were both pretty in the dark as to what our sexual needs were/ had some serious guilt complexes about some "experimenting" we did while we were dating.  The first couple years of our marriage were pretty rocky, with both of us doing some things that although most people wouldn't consider infidelity, definitely damaged our marriage (I had a problem with porn, she drunkenly experimented with another girl).  

We both avoided the discussion we should have had for a long time, but we eventually had some serious talks.  We both knew rebuilding trust was going to be a huge issue, but decided we were going to try to make things work.  

Shortly after that, she told me that her depression was pretty bad and that her PTSD had been pretty unbearable (she experienced sexual abuse), and she told me she would like to move closer to her parents, partially for support and partially because they have health problems that would require someone to care for them eventually anyway.   I agreed to the move, and began slowly preparing.  Then she calls me a few weeks later crying, telling me that she quit her job because her co-workers were treating her badly, and her manager was siding with them.  I told her it was ok, and assured her I wasn't mad.  She asked if we could just rush the move, since we were planning to anyway, and just stay with her parents for a month or two while we got things in order.  Against my better judgement I agreed, and within a week we were there. 

Well both got jobs right away, and everything was going ok.  But right before we were going to move into the place we had found, a serious health emergency caused me to have to leave work for a couple months, setting us back a bit.  We were starting to get back into a good position when we found out she was pregnant.  This was a complete surprise, because she had been told that she would probably never be able to have kids. I didn't know quite how to feel, but I supported her through the whole thing.  Facing the prospect of so much added expense kind of delayed our plans to move though, so we put life on hold for a bit.
  Eventually she approached me with the idea of buying a house with her parents, since she would inevitably be caring for them eventually anyway, and them splitting expenses with us so it wouldn't be so hard on us or them.  Again, against my better judgement I agreed (I really just wanted her to be happy, and I was ok doing whatever would achieve that goal.  So we did, and our baby was born shortly after.  

Things were ok for the first few months, and although we had a few arguments I thought things were ok.  But a few days after our anniversary I found out she had been talking to some other (married) guy.  I found it because she left her phone at home and when I picked it up I saw the messages.  I confronted her, and she admitted it.  She swore it hadn't been going on long, and that they had never been intimate.  But then she started blaming me, saying she was lonely, and that's why she turned to someone else.  I reminded her that I had spent our entire anniversary day (only a few days before) trying to talk to her, and she lied and said that her friend was having some kind of crisis and needed her, when the reality was that she was ignoring me for this guy.  

  At first after this I tried to fix things, and she told me she would cut all contact with the guy.  But she then started saying that she wasn't happy, and that she couldn't let the problems we had in the past go.  She bounced back and forth between wanting to end things and wanting to try and repair things, and since we now had a child I patiently waited, hoping we could fix it.  But eventually it came out that she never even cut contact with the guy, and that a week or so later HE told HER he wanted to cut contact and try to fix his marriage. 

 We were still living together at this point, since we had her parents living with us.  But she said she wanted to just end things.  At this point I  agreed with her completely, and we decided we would just slowly figure stuff out, and separate when we had everything in order.  Later, come to find out, she had been seeing another married guy during this time, and although I wasn't horribly upset, when she told me and asked me if I had been, I told her "no, I have enough respect for you to at least wait until we aren't living together before I do that". It's one of the few times I said something pretty hurtful, and it definitely made my point.  She confessed that she felt like an awful person, and I just kind of told her honestly that I thought her breaking up two marriages and two families just to have what she wanted was pretty shitty.   

 We are finally at the tail end of the whole thing, her parents resent her for forcing them to move (she can't afford the house on her own, even with their help, and neither can I) and for basically making a promise to help take care of them that she's now going back on.   And for my part, I'm just angry that she took so long to decide she didn't want this, and couldn't let the past go.  Was I a perfect husband..... Not by a long shot!  We both fucked up, and agreed to put that behind us.  I resent her, not for wanting a divorce, but for putting me, her parents, and our child in this situation, and waiting until the point that she did to decide she didn't want to be together.   AITA for holding resentment when I damaged our marriage too?
