Please no hate or judgement

On December 28, 2015, me and my boyfriend began dating. I was 15 and he was 18. I turned 16 on March 24, and after then, we decided having sex. Yes we did use condoms and soon after we decided to have a baby. We tried for 3.5 months and finally, October 8, 2015, I got my positive. I was hesitant to tell my parents as for they would possibly forbid us from seeing eachother. They didn't. I then told my BF that we were expecting after I had told my parents. Fast forwarding,...,,, I'm currently 32 weeks pregnant with a beautiful baby boy still cooking. Both our families are very very supportive along with our friends. He works as a shift manager at Taco Bell... Lately he has been different. He doesn't seem to text me GoodMorning or goodnight or even chef in with me to see how my daddy was or is going. I haven't seen him in a week. despite the fact that he is working his ass off for us while I'm finishing up at school.... He does stay up late late at night playing video games and sometimes I have actually caught him sending messages about him and his friends doing dabs and I do smell it on him as well.... I love him but he has been making me so stressed out and anxious. What do I do????
