@Jemjemima I understand it. Mine has been reaching out to me (and I'm caving too right now).
You're still both in the 'limerant, fizzy new passion' stage.
It will last a further a 12/18 months.
The good bits are still good.
The bad stuff (which is the main topic in the thread as none of us have the emotions you do) is always there.
You can always refer back to it in the future.
If you get drawn back just do the following:
1: Don't have him staying at yours barely at all and never let him get cosy for a full long weekend. And never when the teens are there. Keep your space as yours (and the kids). Don't let him encroach on it in any way.
Overnights you can stay at his.
2: Stop discussing the 'future'. Live this relationship in the present. Ignore him if he tries to bring it up.
3: Work on yourself. Social life outside work/ family/ him. Even if it's just 1 evening/ hobby per week. Carve out a social space that's just for you.
4: If he suggests a 50/50 weekend away somewhere just go. You know you will NEVER combine finances with this man. You know he will NEVER live with you for free. You know this and you'll stick with it. His financial future is not your problem to solve.
It took me 4 years post divorce to feel comfortable living solo. All this stuff takes time.
See him as a panacea, a distraction and stay with your gut feeling.
I know I'll get flack for this post but I'm going through similar emotions right now and I understand how our brains try and fight the gut feeling.
His work issues/ no pension issues/ tribunal stuff/ knight in shiny armour stories are not your problems. They're his. You can listen but they're not your issues to solve.
I said it many posts ago. Enjoy the good stuff and discard the bad and at some point the bad will overtake the good and you'll know when that happens 🙂
