my partner has suddenly stopped having sex with me and its even a chore to kiss me also I stay with him as I don't have anywhere to live and he is not cheating on me at least that's a good thing I feel like a celibate lodger?

The three "C's" is what is needed . . .

Why is "Sex - No Sex" an "I'll stay with him" . . . Thing?

Apparently, you've let this go on too long, and now it is resentment that you have. Engage in discussion . . . Healthy discussion is sharing feeleings good or bad.

This is something you and your partner need to work out.  If you can't, then it's time to move on.  You deserve better, don't you think?

Maybe you should talk to HIM about it.

He could be under a lot of stress, and mentally exhausted.
Or he could be tired of your "routine".
Or he could have gotten all he wanted from you, and is trying to figure out a way to get rid of you.

Nobody can read minds.  So again - ask HIM.

Try something like this:  "I have some needs in this relationship and they are currently not being met.  Can we sit down and talk about how we can fix this?"

Hmm .. I would never jump to the conclusion that he has fallen 'out of love' .. because THAT may not have ANYTHING to do with this.

As unusual as loss of interest may seem, it really is not that 'unusual'.  The lack of a show of physical contact or even emotion can be attributed to a number of things from infidelity to underlying health or physiological issues.  Even stress can curb an indiviuals 'interest'. Talk to him, and perhaps it's time for a check up with his doctor.
