A great confusion.

I was dating a person who was mentally affected and had a troubled childhood. It took a while for me to figure it out. Then we later split. But he always wanted to have physical association with me. Now he is dating another girl, but he still wants to be intimate with me. Is this normal ? Any professional reply ?

I am not a professional but since you split, and he wants to be intimate despite dating another girl-it sounds like you cannot be friends but instead will have to go no contact. Sometimes when we have been intimate with someone it is because we are physically attracted and it is unlikely to end whenever we are alone together with them. It is not fair that he wants to be intimate after breaking up with you unless he drops the new gf, talks about your relationship and woos you back. You deserve better than this.

I agree with Hoping, this person is basically cheating on someone else. Try to not get involved in this..

Depends on how you define normal. It's normal for a cheater yea. Instead ask yourself do you want to be involved with some one who is cheating on their girlfriend to be with you?

I agree with the other posters. It's not fair to either you or his gf. You both deserve better. (((hugs)))

I agree with the above posters. It shows lack of character and you deserve better. I would do as Hopingtrying suggested and go no contact.

Agree: no contact.
