Long distance and haven't heard from him in 2 weeks

We have been dating for 5 years engaged the last year and just had a baby girl who is 8 months! We got into a fight and I went off on him via text! He said I need to learn how to talk to him and I haven't heard from him since other than a few text last week! He hasn't checked on our daughter or anything and I'm so upset! Should I call him? The last time I called he just ignored me and that was a week ago! He is so stubborn and stupid because regardless of what we go through we have a damn child together and he act like he doesn't care 
I'm going to go up there in a few weeks because I need him to care for our daughter while I go on a business trip but this is ridiculous 
Apologize for what?
I called the first time and he didn't respond 
Then I called 40 minutes later and he answered
I asked him if he was going to pay for daycare and he said okay but then wanted to bring up the argument before and I told him that was irrelevant I just wanted to discuss our daughter so he got mad and hung up!! He is a straight bitch and I'm so done with his immature ass!!! You don't get to ignore me and our child because you mad about something that has nothing to do with our child! I'm going to give hi
 Until Mothers Day to step up and handle his business, if he doesn't by then I will file for child support! I'm sure he will call me all sorts of spiteful bitches but he still has a responsibility to our child like me so I'm not letting him walk away with no responsibility! I'm so upset but I'll get over it eventually! I just want what's best for my daughter! The nerve of him limiting me and controlling everything
