Is this normal?

[Qwerty09876]

Hi, I'm really looking for some advice about the way I'm feeling.
Been in relationship for 13 years (since I was 17) DC.
The relationship was abusive, physically first few years then emotionally, mentally and financially the whole time!
I ended it end Sep (longest time in whole 13 years)
He has been really nasty and then love bombing me!
In my head and heart I know this is the totally the right thing for me and my DC.
Today I was told someone is interested in me (fancy's me basically) and I have this terrible over whelming guilt (like I'm betraying him Ex)and I don't know why? I've not agreed a date or anything as I don't want too!

I'm feeling very confused and upset cause I don't want to be with him (Ex) but i don't want to be on my own forever either?
I'd be great full for any advice and why I feel like this? I should be cheering but I'm not?! ( but I was before finding out someone was interested) I feel like I'm grieving tbh
Is this normal process of having left an abusive relationship?
What is wrong with me?

I know I will probably find someone 'eventually' so won't be on my own forever as I said in post, I'm just so confused by feeling like this?
I'm hoping I'm just having a shitty day but it's knocked me for two

Yes I can relate. I was with my ex for 10 years I have been single for 3 and the thought of meeting anyone else seems wrong. I don’t even know why as we have been over a long time now! It was an abusive relationship aswell though so maybe that is why
