I need some advice!

Okay so me and my baby daddy aren't together but we're trying to "work" things out. We plan on moving in together as soon as the baby gets here. But I can't help it to get pissed off when he goes out partying every weekend, attending stupid concerts, and spending money on alcohol when he could be saving up for the baby. We live an hour away from each other, but when he comes to town is to party with his dumb friends, he doesn't bother to come see me or ask if I need something. But yet he says he wants to be around and all this bullshit. I wanna go off on him so bad, but I kinda feel like I have no right to since we're not together.

Help please!! :(
