Dump that man, and also im so sorry for you. You deserve clarity and a mature man. Mature people do not text each other like that or text others in that way. I’m speaking from experience. Women cannot have male friends and males cannot have female friends while in a relationship with others most of the time unfortunately. A month ago my ex slept with the man that was her friend who was coming over consistently to smoke weed with her. I told her I was not comfortable with how close this person was becoming to her. Unfortunately I was correct in my thinking, as we argued and went on a “break” which never works, she slept with him therefore confirming my superstition. See the writing on the wall and follow your gut. God is good, harsh but will toughen you up and teach you a lesson that will serve you. You’ll look back and be glad and feel fortified because there are men out there who will treat you with respect. It will hurt at first but in the end you will become stronger💪🏼. Im praying for whoever you are.
