Is this common in a relationship? Or not normal? Please Help!?

Well she'll get over her ex in time. Give her that time and if down the road [I'm talking months and years, not days and weeks] if she still seems like she's still in love with him look into your heart. If she remains in love with him, would it be worth staying around knowing that? Or would you be better off without?

You should leave her while she is still your girlfriend and not wife. She will always love him and it will never be a healthy relationship. She probably just found out that he was better than you in certain things. Sex could be one. Also, don't forget, the fact that he is married makes her want him. It could also be why she thinks she loves him but she will always be curious. Run while you can

it happens....she will get over him and love only you soon enough....if you give her that chance....if you break up not only is that far from mature it ruins her chances of getting over him and loving only you....

this has nothing to do with you or him being better or worse...when a woman gets in a situation two love more than one man at the same time she does not compare them, or the way they do stuff...

every relationship sis unique and it's really not a question of better at stuff or worse at stuff....

you should stay with your gf and do not compare yourself to her ex or any guy....

there is not comparison man......comparison can only happen if you love one guy and do not love other guys....

i can compare other people to the man i ever loved i cannot compare men i loved between themselves.....

TS......there is just no comparison....

this post makes me sad....
