so you have been in a relationship for 6 years, one year of that you were trying to come to Qatar and she was waiting for you but when you finally confirmed your moving here, she bailed out and told you she is leaving Qatar because she cheated you. On the other hand you said you cheated her too, so I assume your cheating came first before she did. So if you were really the perfect man you portray in this story, the one who kept asking her to come back, she must feel an inch of guilt, but it doesnt seem like it.

Hell has no fury like a woman scorned!

Maybe I am wrong all I'm saying every coin has two sides. Trying to get sympathy from others will not help you move on. Goodluck!
