It's incredibly early days yet.
Friends {and my own experience} divorces generally take two years minimum to get over- I felt physically ill after both my break ups - nothing can speed up the time, except the second time my friend lending me the ''Women who love too much'' book really made me ''see'' why I was attracted to the 'Wrong' type of man.
It's like a nasty bout of flu or norovirus..no 'cure', but you just have to ride it out.
However, any contact with the bloke will drag you right back to square one again.
He's no good for you, OP.
I had people tell me the same thing, and thought they were 'Jealous' {that shows how my mind was f&cked up at the time}...but they were bang on right.
Men like this are poison.
I'd really encourage you to read ''Women who love too much''.. it has helped so many women see the truth.
As for the crap feelings.. you just have to ride them out - don't try to fight them- just 'Surf' them, as a surfer rides out big waves.
You won't feel this way for ever.
It's tiring and exhausting, my friend's lovely young adult child has just had a first split from his first 'serious' relationship... He's in pain, but as his mum says ''We all go through it''.... and 99% of us will.
He's a lovely young man, Faithful , hard working and handsome- he will recover...as will you! 👍
