<human>: I'll probably sound like the biggest douchebag ever.

I have been dating (Lin) for a year now and she is a very nice girl and is beautiful. it's just i don't really feel much for her, i did in the beginning but i realized i only liked the idea of a relationship.

I did try to break up with her but everytime i tried i imagined her hurting and crying and couldn't do it. i continued to talk to her and go out i was for sure going to tell her last week but i messed up.

We were watching TV and started making out and it escalated and we did 'it' which felt good. when i saw her at school the next day she gave me the biggest kiss and told me she loved me.

I said it back because i really don't want to hurt her because i care about her but I'm not in love with her. ahat do i do?

Can you condense the text into three sentences or less?
<bot>: i want to break up with my girlfriend but she said sne loves me and i said it back because i don't want to hurt her. what do i do?
