Need advice

Ok so me and my boyfriend have been together for 5 years I was 16 and he was 18. In December we decided to start TTC and we found out In May that I was pregnant everything was fine and going good and last week he told me he "cheated" on me by talking to some girl nothing happend just talked. He says he loves me but Now he is saying that he isn't sure if he wants us to move in together which really hurt me because we tried so hard for this baby and now I just feel like he Doesn't  care about me, I know he loves this baby. What should I do? I really love him and want to try to make things work :/ any advice?
