I just broke off a 3 yrs relationship with my partner for many issues but the main was that i was way more of a giver than her in the relationship, throughout the years i reached a point where it’s even uncomfortable for me to see her apologising to me nd i forgive her instantly where on the other hand i apologise on every little mistake so my pleasure become hers completely and i can’t focus on my own feelings anymore even after the breakup i couldn’t focus on my feelings and i was just thinking about hers , is this a self-esteem problem ? I need your advice along with book suggestions on how to fix my issue . Thank you .
