Problems

My boyfriend has been up in another state for what was meant to be a week now because of a sick relative. Originally it was because his mom needed him and I totally understand wanting to be there as emotional support for your mom. But now he is literally staying at his cousin's house. He's playing freaking house, helping her raise her kids (she's a single parent) and hanging out with her in town at night. I actually tried to convince him to come back this weekend because i missed him so bad and I was going through some stuff. He said no, his mom needed him on Friday so he couldn't leave. Next morning I asked if he got to his mom's yet... No he stayed with his cousin and her kids, because apparently she'd go crazy without his help. The thing that bothers me the most is that he flaked out on his own mother and his girlfriend for his cousin! And now it's been more than a week. I feel so angry and annoyed at him. Because this "cousin" can raise her own kids. She decided to have then. I don't know what to think. I think this is just a rant about what was going on. But if you have any thoughts about this please tell me.
