I don’t think it all needs to be so black and white. Sometimes when you don’t know what to do, it’s best to do nothing for a while (or very little). Just do some gardening or sewing instead.
One thing I would personally do though is to call some time on your current relationship. Definitely don’t rush into moving house with him or back home, take a little time to ponder what’s next for you. Do a little gardening instead.
As for your ex H, who’s to know? If he really, truly feels the same way you do in time, ends his relationship and wants to try again with you, if you’re both committed to it then that’s your decision to make. People do
reunite, some people remarry. Only time will tell and only you can know whether that’s going to be right for you. I would definitely not be initiating contact with him though. If someone wants to be with you, they will find a way. He should be putting the effort in if he wants to reunite and he should leave you in no doubt of what he wants and his actions should reflect his words. Proceed cautiously and first and foremost, protect your heart.
But mostly importantly, be alone for a while. I’m a similar age to you and have had to adapt to being single since my H left in 2019 (our 3 children live with me). I am cherishing the time I have now to focus on the children, work and my hobbies.
Maybe it’s naive but I have faith that I’ll find love again at some point in the future but right now, single life is fine. I like having the comfy bed to myself. I like just being left alone to do some gardening.
Keep the faith. Look after yourself. Take your time. You’ll be fine.
