I met a guy a month ago. We get on great & the S*x is amazing. He is separated & has a daughter with his ex.

I said from day one, I wanted it to be casual thing between us, that I wasn't looking for a relationship. However my feelings have changed now.

He has told me he can't fall in love with me, as it would be very easy for him to do so.

When I mentioned that I don't want things to be casual, he told me he doesn't want a relationship, he's happy on his own & for things to be the way they were.

He has now gone off for a week to visit his ex & his daughter, he siad when he gets back he will see where things are.

Im feeling so down, sad, depressed, Im really mad for him (I know only after a month) It's the longest week ever!

Any advise would be appreciated

thanks

1 month and you're having sex and have fallen for him and he is off visiting his ex and his daughter, plus he does not want a relationship.
You need to walk away from this now. Not a good situation.
