Someone advice pleas

So I’ve been with my partner for 4 months.

His brought my daughter up as his own and been lovely.

However, he doesn’t kiss me or cuddle me and hasn’t had sex with me for over a month now.

He says it ‘hurts’ him but is willing to have an*l which I do not want!

I’ve told him how I’ve felt and he says it’s not him BUT he used to do it?

I cry almost every night as I don’t feel wanted.

Am I over reacting ? What’s your thoughts?

I’m struggling.
