my boyfriend and i have stopped becoming intimate. (shame guilt, need help)

my boyfriend and i are both 16 and have been together for 5 months. we are both christian, however, when we got together i felt i had grown farther from God for some other reasons. but when we got together, I had in my mind that I wasn’t going to have sex until marriage or until i was a lot older. this didn’t happen. when my boyfriend suggested it i said it went against both our morals. but my boyfriend and i were both overcome with lust and had sex anyways, which i didn’t see as too big of a deal religion wise. it started becoming a regular thing. however, just yesterday, my boyfriend came to the conclusion that he wants to stop doing ANYTHING sexual, only making out. he says he wants to become closer with God. I was really happy he made this decision because I too want to get closer with Christ. But I have a lot of shame and guilt around not being a virgin anymore. and I feel ashamed because my boyfriend suggested it, not me. after it becoming a regular thing, it’s going to be very difficult for me to stop so suddenly even if i know it’s the right thing to do. i don’t want to break up with him. i love him and we’re the perfect match. but i do feel some sort of confusion and frustration.

how can i deal with this? i really do want to get closer with God but I don’t know how. i feel like im growing apart from Him and I don’t know how to stop it.
