You just met this guy. It’s not like your husband or long term partner unexpectedly developed an issue, sure spouses or long term partners would stick around and see if it could be worked on.

You dated a guy fairly briefly, portion of which he was doing his own thing like traveling and attending events without you, being distant, being rude calling you needy and clingy, you spend very little time together and don’t even talk much (that one night a week he’d come to spend the night-is it to have sex?), yiu dint talk during the day (he doesn contact you) etc etc

He isn’t a suitable dating companion from the very beginning but you are now determined to change him into someone else. Someone he isn’t.

Were your other relationships happy and healthy? Or they were all with emotionally unavailable men? What does your therapist say?
