My girlfriends mom saw us kiss, now we dont know what to do..?

ok so last week tuesday, i was at my girlfriends cousins house and we were in the computer room and we kissed and her mom walked it and told me i had to go home and basically she told my girlfriend jennifer, that she needs her to stop talking to me. her parents didnt know i was bi or a or whatever and her either. so basically jennifer and her parents had a talk and her dad is supportive even though it kinda hurts him, her uncle and aunt are supportive too but her mom is acting like an ignorant b*tch. she wont let her go anywhere, she wont let me come over, and calls jennifer stupid and says she doesnt think, and basically makes jennifer feel like crap because of who she is and it sucks that my girl has to go through that just because her mom doesnt accept her as she is. basically her mom wants jennifer to be what she wants her to be, she shouldnt care what jennifer is, as long as she is happy you know, so today is our 2 months and we cant see each other at all and it sucks, we dont know what to say or do, i mean she is going to tell her parents that we kissed because it was in the moment and it wont happen again and that they can trust us but her dad will be ok with it, its just her mom, shes the churchy type and harsh to. and plus if they are ok with it and i can go over, itll be very awkward and i hate awkwardness, so help me pleaseeeeeeee thank you :]
