Reading your last post OP....
His quality of love is not the right fit for you - you say he definitely loves you in his own way - but even that way of saying it reveals that the way YOU'D like to be loved is not his way, and you have had to flex to tolerate it.
If the shoes don't fit, it's no good HOW pretty they are, you will not want to reach for them for a full day and night out - they irritate, no matter how much you don't want them to.
That's what this guy seems like to me...
Then -
He needs you because you're his mummy. His safe place. Always there, good quality love and adoration. It's not sexy. (For you.) You're not his mum, you're a woman with feelings and needs, not just there to make him feel good. I sometimes think that some men want a woman to adore them and to provide a level homely environment, food, Sunday happiness etc and then they want to chase other women too.
I think if this man adored you properly, he would not even have room for thoughts of other women.
I'm so sorry to be writing this btw and God knows I've been there.
