okay well ive gone out with this girl once before and weve been like getting intimate and hangin out for awhile now lets call her jodi. But she told me awhile ago she wasnt ready for a relationship yet because her ex boyfriend used to abuse her and stuff so on. So lately me and her have been great its like are connection got stronger well i went to montreal with some friends and i ended up having with this girl. I feel so god damn bad i seen jodi when i got home and she was so happy to see me we watched a movie and when she was lieng down on me i felt so teary eyed because shes my girl and i feel so bad. But me and jodi arent a couple so im aloud to do things i want as she is but i feel so bad i hate myself and im not forgetting it what should i do telling her will just hurt her a lot and were not dating its not like i did anything really wrong its just god i feel soo bad like the ped 2 days ive realized i love her and its not because i feel bad i just kno it because i want to do whatever i can not to hurt her
