will things go back to normal

Lauren
My bf and I were doing great (were 17 almost 18) until his mom found out we had sex (last summer) and things have been going downhill since. We fought a lot, we broke up for a couple weeks in may. And it was really bad. Now we're together again and it's gonna be our year and a half on Saturday. 
He Says he still loves me so much and I make him happy, but it's not the same. He used to always call me beautiful and go out of his way to do so many things for me, I mean he still calls me beautiful but not as often. We still kinda argue and stuff sometimes. And he can't Always hang out now. 
I'm scared he's falling out of love with me. Like he clearly still cares, but cares about the wrong things i guess. 
I'm terrified things won't go back to normal (us hanging out a lot, not arguing a lot, and. Aunt normal texting convos) part of me thinks it's doomed part of me thinks it's gonna be ok. But it's so hard to be positive when I feel so sad bc we barely text and idk it's not the same
I've talked to him about it and he says everything good with us but idk
What do I do? I want the old us back. 
I'm scared I'm gonna lose him for good, I love him and I'll always have a special place in my heart for him bc he's my first love
