Ok. I know I said I wouldn't keep going with pointless non updates. But here I am.
I am reading and taking on board all your comments.
I'm taking a while to catch up - it's incredibly difficult for me to accept what he is and that it's completely over. But I do. I honestly do.
I've told him I'll be starting divorce proceedings next week. He was all what's the rush? Blah blah. I said that now it's over, and it is, I need to move quickly - I can't bear things as they are. I asked him to imagine if the roles were reversed and it was HIM sitting waiting whilst he cultivates new relationship or if it fails to come back and wait whilst I look for the next one and we go round the circle again.
I pointed out that he may be entitled to some things legally, but not morally and how can he look himself in mirror knowing he's paid for nothing and then acts like this and tries to take it away from us.
Our mutual friends stopped in car as I was returning from walking dog and asked how I was. So I told them.
He said that surely he should have been one to tell them. I said you were showing no signs of it so I did you a favour.
He's too lazy, too skint, too stupid and too confident that I will fix things for him to seek legal advice.
By his return I will have the ball rolling and then it's just a question of suck it and see.
He will probably just return to his parents when sees that I'm not letting him stay here.
If he won't leave then I'll just ghost him until I can sort something.
Our son will be told at the point that he's got a definite plan in place for leaving - to wherever that may be.
Our son will be told that we love him and that what we do doesn't detract from that.
I will facilitate and support their relationship but I don't force it.
This time I really AM listening to advice and I will take it.
I realise that the man I loved so much hasn't been around for years. He's been seeking confidence boosts and attention online forever, it's never stopped. He loves / loved me as much as he is capable of. As an intrinsically stupid and selfish man - that love amounts to not much at all.
I reiterate that I WILL seek legal advice. I will not back down to him.
Thanks again to everybody who has posted.
