Whatever the situation is, be responsible. U're in a relationship so u should respect ur gf and be faithful till the end. If u see it not working out with her, end the relationship and have sometime for urself before jumping into another one. ሁሉ አማረሽን ገበያ አታውጧት እንደተባለው rather than acting like a kid changing toys every second, be a mature and responsible person
