heartbroken

So my baby daddy and I have been together for about 5 years now we have a 3 year old. We haven't had the best relationship, we broke up for almost a year a few months ago he ask for me back!! Just know I truly love him not just that I have faith in the lord, I have faith that he can change me and my bad ways as well as him. I have been trying so hard to be a batter person in general!! ..... we got a house together 2 hours ways from home because he was offered a job I helped him out a lot on getting our house. I'm still living in our home town and go visit on my days off. I'm 5 weeks pregnant with our second baby ......... he has been asking me to get pregnant..... ok now I'm pregnant and he's ignoring me and i try to go see him every chance I get but he doesn't do the same for me !! He goes out with his friends to bars and just leaves me by my self no call not text at my mom with our kid..... I try to tell him that it sucks how he makes me feel but all he does is tell excuses on why he couldn't come to see us!!!! And then tells me that he's done on how I'm acting !! I mean I'm not perfect, but I tell him how I feel and how maybe he can do thing different!!! I can't get thought to him !! Im sacred  only 5 weeks and no support feeling so emotional and stressed and sad!!!!
