No I have no kids and he has no kids either.
He says it will help us to share bills etc but I have enough money to manage my house and money left over for spends etc
We have had a few weekends away and I do honestly love him but after 3 nights with him ..I'm pleased for a bit of peace
@brinkopopo
You say you really honestly do love him, but are 'pleased for a bit of peace.' This doesn't bode well, and is a bit of an oxymoron to be honest. If you really 'honestly did love him' I don't feel like you should think of the time away from him as 'peace.' That doesn't bode well to be honest.
As almost ALL posters have said, do NOT let this man move in. He sounds weirdly pushy for some reason.
This reminds me sooooo much of a friend of mine who was widowed in 2016, (at 53,) and after 33 years in the relationship (30 married) she was happy to stay single. She was pursued by a man in her village who rented privately. (She and her DH had been in the same social housing house for 23 years, and had very cheap rent, and a lifetime tenancy in a lovely area.)
She decided to go for a drink with this man after he lovebombed her for about a month. After they had dated for some 6 or 7 weeks and seen each other around 15 times, he said 'my tenancy ends on my flat soon, we get on so well that it makes perfect sense for me to move in with you. Just think of the money we will save!' 
She was like
She told me she was gobsmacked that he had even suggested it, as she had had food in her fridge longer than they had been dating!
She was definitely against it, and went in with a light-hearted 'no you can't move in, are you mad?!'
He was like 'eh?'
and was really irked that she said no. He stormed off in a temper. She ignored him and put it down to a petty strop.
Next day, a letter dropped through her letterbox - for him - redirected from his current property that had its tenancy end in about a week. Cheeky fucker had got his mail redirected! Before even talking about moving in with my friend.
When she told him again - more sternly this time - that he can NOT move in, he got really arsey and aggressive and told her she was making him homeless!
She had a hell of a game trying to get Royal Mail to cancel the redirection, and convince people she had NOT agreed to him moving in. He had lied to so many people, and told them she had let him down! Awful man. And yes, she DID dump him!
Hope you have the sense to tell him NO brinkopop.
