I found out my boyfriend cheated on me. I have decided to try to give this relationship another shot, but I can’t help but continuously wonder if he thought she was sexier, was she better than me in bed, etc. My esteem took a nosedive as well. How do I get past the thoughts of him with this other girl and comparing myself to her? Has anyone ever stayed with their boyfriend after he cheated on you? How did you get past it and did the relationship last?

Whenever there is cheating in any relationship it causes you to mistrust your partner if you ever decide to go back with them.
What you need to do is try to get past this, if you really want to make things work.
Healing your heart would be a very hurtful process and not many couples last after affairs. You have to ask yourself, is it worth it. You have to look out for your best interest, no one else would do that for you.
Now you have to ask yourself, do you still love him?
If you need more assistance, would strongly advise that you read my article on ‘Affairs’, it should help.

Leave him, no questions asked, do not pass go and do not collect $200.
What is wrong with you!? He clearly doesn’t want you since he cheated. Leave the bastard already!
leave him FOREVER
Leave that motherfcker…
Do you want to live your life wondering about a complete stranger and always comparing yourself to her ?
That’s not a happy life and def won’t make a happy relationship with your bf.
Girls take their cheating bf’s back becuz they think if they keep him – they are beating the other gal he cheated on with. That’s a dumb reason .
There is no happiness there .
