Kids??

Guys I need some help..I’ve been with this guy for a while and we’re super into eachother..but he has a kid with someone else. She’s a year and a half old and he hasn’t seen her in MONTHS because her mom is a total bitch and is jealous that we’re finally public..the problem is that I’ve been so spoiled spending time with just him, that I don’t like the idea of the baby being around. He finally got visitation with her after I pushed him to and everything is going to change now. I’m selfish, I know, and I REALLY want him to have a great relationship with his daughter, but I don’t want kids right now and we’ve been so used to talking about a future involving JUST us, that the idea of having a kid just isn’t what I want.. I want him to have a relationship with her because is definitely NOT my place to tell him otherwise, but I don’t really know how to get used to the idea of her being around. I love him so much and I would NEVER EVER make him choose between us, I just need help with how to deal with it changing all of the sudden. I’ve talked to a few girlfriends about it but nobody really understands how I’m feeling. I’m so torn between just letting him go and staying to work it out. I love him so much and he’s seriously my best friend, I can’t even imagine living my life without him. Help please. ☹️
