Every time fight happens he yells at me abuses me , my family , my frnds (not in front of them) blames me which arent related to the current fight most of them are false blames and later he says sorry for straight 3 - 4 dys and says he won’t do that again and my heart melts & i forgive and then this happens again. I am really tired from around 2.5 years this is repeatative situation. We both are very attached to each other so He won’t allow me to breakup whenever i say i want to breakup he blames me for no reason and bring literally 2 years past fights .
