Home chore is and never should be an enough reason to keep a woman let alone wife her. Men need to stop taking shits in the name of she knows how to cook blah blah blah.
Bro the moment you see her give out number, If you value yourself and have a sense of self-esteem for yourself, the best thing to do is to cut her off { mentally, physically, emotionally and financially }. Telling her to block the man is like trying to stop a moving train. One thing you need to know about women is that they are not stupid, they sure do know what they are doing.
As a man of value, the day you saw her giving out number is the day you know that you are not the one, you are not enough and you will never be enough. She's definitely looking for someone better and is holding on to you temporarily for the immediate benefits you provide.
Knowing she unblocked him, calls him, chat regularly with him and also having the knowledge that she slept with him is a big Disrespect to your masculinity. She disrespected you by unblocking the number after you have INSTRUCTED her to block it, You meant nothing to her why won't she sleep with someone else, have you cut her off earlier you would have avoided the disrespect and emotional drawdown that followed up.

My advise for you is:
-Learn the difference between attraction and arousal and you'll understand women better
-Focus on yourself more, learn to love yourself more, learn to enjoy your own space without female presence in it
-Hit the gym, exercise more
-Prioritize your life's work (purpose) over women
-Elevate your sex game
-If you are not ready for marriage never commit to any girl, have sex with them and be ready to ditch them off whenever you feel like, never feel bad to NEXT any girl
-Get financial freedom
-Enjoy life on your own ( trust me sex is not everything )
-Respect a good woman but treat a LovePeddler like a LovePeddler she'll thank you more than you trying to invest emotionally on her
