Thank you both so very much for your advice and honesty.

I really appreciate it so very much!
I really needed to hear that from someone, in my heart I know you are right.
My children are everything to me and I will do my best for them, and try to for myself as well.
I'm going to keep seeing my psychologist, he's been working with me a lot the past 6 months to stop being so passive and be more assertive with my life.
I'm also on a waiting list for another psyc who deals more with trauma and certain therapies.
There are a few community organisations that offer support for women, I'll see if I can get in touch with them about how I should approach everything with regards my relationship.
Thank you for sharing all those links!
It put a lot of things into perspective, especially the advice from Cheryl Strayed.
