I still have feelings for my ex..

When I was 20 I started seeing a 34 year old man. I am now 23, he’s 37 and we are both in new relationships.

When I started seeing him, he was fresh (a month or so) out of an 8 year relationship which ended because she cheated on him. I believe I was mainly a band aid for him while he got over her but I stuck around because he was very good to me for the majority of the time. We acted as though we were a couple, did things together, I met his family and all of his friends and regularly did the ‘housewife’ thing.

We lived in seperate cities and I would drive 2 hours ever Friday to spend the weekend with him. This went on for about 3 months before he called me one day before I was due to leave to see him and told me that he needed time and space for himself. I didn’t hear from him for 4 months after that. I had moved on with my life when he popped up again. Now I can’t break contact with him. I know I still have feelings for him and I am in a relationship with another man.

Am I wrong for still having him in my life?
