<human>: Can you succinctly summarize the text in 1-3 sentences?

My girlfriend (20F) and I (21M) have been dating since last December. I went to visit her parents place and we needed to let go of some tension since we are on break from college and haven't seen one another since May. We did the deed at some smoky seedy "daytime hotel" near her parents place and lied to them about where we were.

After I left to return home, somehow, her parents found out what we did. They're religious, and she is less so, and they're freaking out. They may not send her back to school (despite paying tuition already), they want to go to family therapy, and they say I'll never love her because of what we did (we haven't said "I love you"). They say loads of negative things about me despite not knowing me (or getting to know me during the weekend).

I get it--we fucked up. It was disrespectful to lie to them and we both regret ever even going. The truth of the matter is that neither of us wanted to back down and we were both pretty shaken by the vibe of the seedy motel and how we felt afterwards, not to mention the lying.

They've always been overbearing and disapprove of her changing from a quiet studious girl who moved around a lot as a child/teen into someone who feels secure in a location (she won't move where she spends most of her time when she is in college) and has more friends and a bigger social life. She still studies hard and works tirelessly for great grades, but her parents also don't see how much happier she has been since that change began (long before we began to date).

What do I do now? How can I help to fix this?
<bot>: Lied to my girlfriend's parents about where we were so that we could have sex, they found out right after I left. I want to make things better because I realize it was a colossal fuck up.
