I was in phone this morning with my partner and I accidentally said what the used of marrying with u but I don't mean to say that now he is not answering my call at all.

"used of marrying with you" sorry no idea at all what you are talking about.

Text her, call her, send her flowers, tell her you are stupid and sorry, ** does not matter I don't understand what you said, just take the fault and beg forgiveness
