I have been with my partner for over 4 years and it has had its up and downs. We don't live together and I live with my two children which are not his, but they have become pretty attached to him as he has to them. I feel like the relationship has run it's course and I don't see a future with him that he does want. I feel lots of pressure to live with him, get married and have kids and I want all of those things, but I know it's not with him. I feel I should just be single for a while and find out who I am on my own, as I've never been single for long. I have worked on myself so much the past year and so proud of what I have managed, but he very much has no ambition and I just don't find him attractive anymore and feel he is always trying to sabotage what I am working towards. The problem is when I did end things last year he tried to kill himself. I worry about his mental health and the fact he has PTSD.
