I got this girl and loved hard. She cheated on m recently and forgave her...I am soo insecure and the fact that she went upcountry for a burial and she is not available. It haw been a day we haven't talked. I want to leave her but looks like I am attached.
I'm not an expert but if you can't trust someone you need to work on rebuilding that trust or call it quits if the both of you are willing to do the work..
If you do not trust someone, leave them. Also talk to many girls it will help you get over your insecurities by showing you there are options out there. You can talk to many ladies without necessarily cheating, that way you get comfortable in knowing you can pull girls and when your gf sees this she will appreciate you more.
You need to figure out the reason behind her cheating cause chances are it will help you predict whether it might happen again , also if the reason is something that can be corrected and you both work on it, you'll find peace no matter how little and that way you can start rebuilding your trust in her slowly by slowly
Otherwise if it turns out to be a hopeless case , choose yourself no matter how much you love her and move on , not easy but with time you'll get results, positive results I hope
