Old love look to me to be satisfied

I have a wife and one year old son. Before having sex with ex-girlfriend I never thought going to bed with a woman other than his wife. About half a year ago ex-girlfriend surprise messaging, call visit (she knows I have a wife and child and then). Through a twice talked to drink water, she actively wanted to join me in the hostel.

4 years ago she and I love each other, are almost a year and then parted. The few times the phoneactive, meet so I betrayed my wife, on the House with the old man. Both times she are very desire it and I also enthusiastically respond. She said the last time love another person but about the bed not forget me, just hope I can believe with her on, she just has that.

Toward me twice on the finished House now feel very regretful because betrayed his wife, so 3 months now not contact her. There are only few times I tell this story not messaging can last forever, suggest she try to forget me and find yourself the right life. She still fervently want to prove I do that, I don't know how to suggest. Looking forward to everyone for the comments. Please thank.=
