First time poster and I literally don't know where else to ask.
Married my first boyfriend age 19. Together over 20 years but the relationship was quite abusive mentally and emotionally. He's changing etc and hasn't been treating me badly in about 3 years.
In the last year this guy started in work and we just clicked. He makes me feel so good about myself, will compliment my hair, we can chat and have a laugh, takes a genuine interest in me. We can chat and joke for ages but this is where is gets complicated.
He's extra nice to me, there has been some innuendo jokes from time to time. He knows of the abuse I have been through with my husband etc and he was supportive making sure I was OK.
I have no experience in this and I have never felt the way I do about this guy.
I am not a looker and have been told for years I am an embarrassment. There is no way he could be attracted to me and I assume its just banter and him being friendly.
Leaving my husband isn't an option for various reasons I can't explain but if I thought I would get a chance with this guy I would take it which isn't me at all

.
Do I ask this guy to stop being so nice to me and giving me compliments as it's giving me the wrong idea.
I feel like I'm going insane with these feelings and need them to go away.
Really appreciate any advice x
