He's messing with my head after split.

[ImSoUnoriginal]

Please tell me this isn't normal!
I've split with my partner nearly 2 weeks ago (his instigation but neither of us were happy). We have a 18mth old and I own the house. He is living here still as he has no money. He's waiting for me to get him some, as he put money in to this place and lots of work.
The reason for the split is lack of sex for him and for me, I think he's overbearing, makes digs at me and is negative, which makes me not want to have sex. It's a bit of a vicious circle as no sex makes him grumpier.
So that's the situation.
My issue is that he will make digs and be snappy with me and then say I'm over sensitive. He moans at me about the sex thing (despite us having gone over this and agreed to split) frequently during discussions about us splitting up (I think this is pointless as we are over). The next minute he's giving me a hug or kissing me. It's confusing the hell outta me.
I'm writing on here as he did it again. I'm in bed, he came upstairs and asked if I fancied a hug. I said ok then (I know, I should have said no) and rather than laying on top of the duvet and giving me a quick hug, he got in the bed and started stroking my back under my top. I have to admit I just held him and didn't reciprocate and instead started crying. I'm sad about all of this and that made me sadder. He asked why I was crying and I said it made me sad. He got affronted. I said didn't he think it was weird to cuddle like that after splitting. He just complained I didn't hug him back and I have no feelings.
I tried to explain that I think it's odd to be snappy, make digs (most of which I ignore but I don't like) and be mean, then to give me a long kiss (two nights ago) when we have broken up. He said he can't help it, he's permanently horny through lack of sex. I said that didn't matter and if he wanted sex or anything he should be looking elsewhere as we're not together now. He got huffy.
I want to keep things as civil as possible for my sons sake. They adore each other.
I'm right though aren't I? There should be boundaries now, shouldn't there?
He can't tell me, 8 hours ago, that he's angry with himself for staying with me so long, then expect cuddles?
This is hard anyway but he's making it harder.
Sorry. I'm aware this is a bit rambling but I'm in a bit of a muddle.
Oh and I didn't stop the kiss the other night, as I was too shocked and confused.
Help.

It sounds like it is time for him to leave - this situation is messed up. I say there no one else he can go and live with? This thing of him getting to be horrible to you because you are separated, but then wants to have sex with you must be hard to put up with.

You own the house. Kick him the fuck out. Him not having money is not your problem.

He doesn't believe you have split up and he didn't come to hug you - he came to try and get his leg over.

I also don't think you are splitting because of a lack of sex. I think you are waking up to his manchild, abusive crap and you are a tough lady who won't have it. Good on you!

Now give him 30 days notice to vacate (or rather see SHELTER guidelines on eviction) and stick to it. Go see a solicitor regarding your rights with the house etc. You don't want him putting any financial claims in. Make sure you set up child support arrangements and custody too. Make this all official. Once you do, you will find he isn't playing nice anymore. Be prepared.

Don't allow any touching. He is now a lodger. Stop cooking and cleaning for him. He will never leave if he is having all his meals made, laundry done and cleaning sorted!

You are so right to split with him. You won't ever change him and you deserve to be with someone who adores you.

He doesn't want hugs or cuddles, he is hoping you give in and he gets sex.

You are in control of this situation. Why are you saying yes to kissing and hugs? Get him to move out.

He's even told you he can't help it because he wants sex.

Get him out asap and stop allowing the kissing and hugging.

You need to kick him out ASAP.

Thanks folks.
I can't just kick him out. I wouldn't do that to him (despite him being a dick at times). I'm ok, as I know it will end sometime. Our house was a mess before I bought it and he did all the work and made it suitable to live in again. I do owe him something for that. He has no one he could live with. He has no close friends. He's a fantastic dad and our boy loves him. I'm not going to make it hard for them to have a good relationship. More than anything, I guess I just wanted to know I wasn't going nuts and this wasn't normal behaviour when splitting up. Which you have confirmed. He's promised he won't kiss or hug me (I didn't even mind a normal friendly hug but this is preferable) anymore. Obviously he made it sound like I was being wildly unreasonable and over emotional again. It's weird, he didn't used to like talking about things and kept everything bottled up but now he seems to want to rehash all our problems, which seems irrelevant to me now we are breaking up. I offered to go to counselling several times during our relationship but he's always refused, saying he's a very private person (which he is) and wouldn't get anything out of it.
Ah well, grin and bear it, while trying to keep things normal for the toddler.
Thank you everyone. You have made me feel slightly more sane after a broken nights sleep.
