Is AUTHOR wrong in the post ? POST : Hi everyone! Long time lurker, first time posting. 

My husband and I (38M, 31F) have a seemingly perfect relationship outside of typical work/children stressors. We've been together and married for approximately 4.5 years after waiting only a few months to get married. We communicate often, and well.  We trust each other, completely. Any time an ex might slide into DM's for any reason, it's brought forward. 

I admittedly read A LOT of r/relationship_advice. Idk why, really. Call it a guilty pleasure. I get tired of the typical mundane droll that is FB, IG, etc, so I often turn to Reddit for something more stimulating.

To get to the point, I started to see a pattern in the last several days on RA where the OP's cite that their significant other was cheating after several years (lets say 6+) of supposed monogamy, and they claimed to have not known their were any issues in their relationship that would have caused the SO to act out in that way. 

This, in turn, prompted me to shoot my hubs a text to "check the oil" on our marriage, as it were. We had a baby a few months ago, (my first, his third- we have custody of his other two) and we've been adjusting to the changes, of course. I asked him if there was anything he needed, or was lacking from me, whether it be doing more around the house, doing more things with him, or yes, even physical aspects of our relationship. This lead to him saying no, he's good (to paraphrase) and then make jokes about more sexual acts, of which I will spare you.

Okay, cool. 

I pick up the baby from my mom's, and am on the way home when I realize that, heyyyy, he never asked me if I was good. He answered my question with "nope, we're good, more sex." And went about his way. So I point this out, and he replies with "oh, so we're fighting today. LoL jk jk." 

We talked it out once I got home, and he claims to have been planning to have a sincere conversation about it once all of the kids were in bed for the night. Maybe true, maybe just something an inconsiderate husband might say to cover his ass. 

AITA for being miffed about the fact that he was seemingly unconcerned about my feelings until I pointed it out?
