Me an this girl have been together for about a year and we have had 3 breakups and the 2 breakup I thought she was gone fer sure. So I went out and had sex with a girl she happens to know and she found out about it and all of the sudden breaks up with me but she says she still loves me and misses me and she wants to work it out but In time. But she's not acting like she wants to what do I do?

Trying to work through a problem that involves sex (even though you were technically not together) outside the relationship is all but impossible to overcome is what I have seen time and time again.

I suggest you both give this much thought and communication before you make the decision one way or the other to be as sure as possible it can be left behind .

If it is not , the chances of it being the downfall of the relationship are great.

That is the cold hard truth as I see it.
