My girlfriend left me for another but after 2months she came back. I love her so much that I accepted her even after she told that they had sex. But there is nothing like before no fun no happiness. Like something is wrong.

If it isn't the relationship you want, then get out. You were broken up, so she wasn't cheating. If you can't accept that she had sex with another person, then you need to end the relationship.

Its not from my side she still talk to that guy more than me. She is kind of ignoring me. The day she came back said I left everything for you and m back. I am only yours. I accepted her even after she did so bad to me in these 2 months. Next day she said I had sex with that guy I said no worries you still have same respect, next day again she started talking to him. And finally so talk to him whole day and don't have time for single text to me. With in three days she started playing with me. When say clear what you want den she says I don't know.
