Search Results: getting married after 3 months

So in the past 6 months, I moved back in with my BF. I have 2 kids (previous relationship) and commute 2 hours round trip to work M-F. He lives in housing provided by his job and walks to work. I leave before he wakes up, and get home about two hours after he gets off. So, 7-9pm M-F (except Wednesday when I have class) is the only time I have with him awake and I have to cook dinner. We live on a reservation and I'm a teacher on another part of the rez. My district is requiring an additional endorsement, why Im gone Wed. I miss him and want to spend time with him. I rarely get to see him. Problem, the time I am home, he eats and than usually goes to his neighbors. He didn't come home last night, this is probably the 6th time he's spent the night at her house. His phone is off (he always says it dies because they watch YouTube). I went over and knocked several times tonight, no answer. Last weekend I left for 4 days and stayed with family (3 hours away) because I was so upset at all the time he spends with her.

He says I'm overreacting. That she's older and he'd never do anything with her. He also said we are not married and he doesn't have to answer to me. He works with her in the same department, every week, and texts her more than me. She is getting a divorce and he said his friend needs him. He also says I'm being clingy expecting to spend time with him (I'm rarely home). He said he loves me and the fact that I am in his house is enough to prove it. What is going on with him from a guys perspective? He says it's innocent. I admit I'm jealous. He says it's hard to be around my kids, he just needs a break.

Back story: We have been together almost 4 years and this is the 2nd time we've lived together. A year ago he cheated with a co-worker and before that, he was seeing me and another girl behind my back while we were supposed to be exclusive, but broke up (I ended up with an STI because of that situation). He swears he has been faithful, but
