All this sudden realisation that he loves you and this is due to losing you?
Hahahahaha. So losing you when you split up before didn't make him realise?
he was busy buying your 'Dream Home' but without any thought that he was actually serious about your relationship???
Doesn't really add up, does it?
No - because to him, having you in a serious relationship means he still makes careful pre-meditated plans (and sets up an elaborate deceit around the football match, plans not to come over...) to sleep with prostitutes.
You are right, you can't go back to him, no, because in his mind he has got away with it 3 times so he believes he can get away with it again. Especially because now your DS is older he can use him to guilt trip you to stay. He knows now that he can talk you round and you wouldn't chuck him out for good - so he will never stop his behaviour.
That last message is full of guilt tripping over your DS.
And...he lies. Had you not seen the woman go into his house, he would have lied and lied. And got away with it again.
Hahah - can you imagine him going away for 3 weeks and not paying for sex? This is what he does. You can never trust him again.
My guess is he is addicted to this paid for sex (and porn, too). He doesn't say anything ab out HOW he would transform himself. He has a poor record for it so far. His only solution is that being with you would help him transform himself. Fat Chance, he had two failed attempts.
And I also suspect that you are addicted to him, because you don't know how to live without him.
Addiction is not healthy. It leads to decisions that will damage your life very badly. Don't see him on Christmas Day - he will talk you round, get sentimental...
You are young. You have your whole life ahead of you.
Free yourself.
Heal yourself
Build yourself up
Go out there and find happiness and contentment with a man who knows how to love, and is honest.
