To pre-emphasize I'm m 35. Gf is 31-2. Her kid is male 11. 
I've been living with these 2 since we reconnected after a shitty ass high school romance where she had me walk to friend/exes/fling/aka spoiler baby daddy and made out with him while I was standing watching from sidewalk.
I gave it up at the time of summer vacation. She was prolly 6-7 months preggers, I didn't give up the ghost until school started she was showing and still didn't want to give me time of day.
FF to my next gf type experience of a pill popping money hungry tease. She had gods blessing where her mother committed suicide when she was 16* and had to raise her siblings alone. Of course after playing my heart strings I signed a lease to an apartment fur her and her kids/siblings(her only blood child wad taken by the state to live with its dad).
I kept leanding her money to stay afloat whilst kinda getting to spend time/get affectionate (from first person view I can't say how it did or didn't effect her or her feelings.) During the brief time of money transfer.
FF her convicted bf got out of jail lived with her and the kid ins apartment with only my name on lease, ended up back in jail 2 months later which she immediately minimizedcontact with me. Afterward she got a new apartment she didn't need me for a new lease cuz dumb ass me was still on old one and had to pay off 2k in over due rent later. 
Has me come over and try and live with her and kids/siblings when I either go crazy in the head as hear shit or I hear her gong thru with some b.s. cheating on me on the apartment literatly across the hall. I leave in a flurry of arguments nothing on the apartments is mine so I just get up and go after loud street argument.
FF NOWISH... I've been dating/living with the girl from different baby daddy in scene 1. She had found me on Facebook and stared talking. Said her roommate was a creepy trying to busy in on her during shower or other things. (Now I wonder if he wasn't her boyfriend until she had upgraded and is all lies).
He moved out in less then a month and i was in. All through out the first year i knew she was cheating on me. Going to her friend Zach and staying the night coming back freshly showered (which she does now, and I think she abuses her ps cuz she literally feel asleep sitting up). I complained cried  fought she won I gave up and am now realizing I'm stuck in the same shit I got out of. So aita for going full circle? Are we all the assholes and life is hard I just need to toughen up? I feel we are all the asshole but don't let my one sided speil sway you.
