Hi ladies n gents
First time posting on here, I need some helpful advice, feeling really low.me and my fiancé of 5 years split up in September. At the time my mum was very sick and she passed away in November. During the end of our relationship, I didn't grieve it. I felt nothing because my whole life evolved around what was happening with my mum. Over Christmas me and my ex starting getting on so well and I really thought we would get back together.
Then a week later he said he had met someone and was in a relationship. I felt as thought I had been crushed. I haven't been this heartbroken. Since I was 15. I forgot how awful it was! I am happy that he's found happiness with someone else but it kills me that she makes him happy and I didn't. To make things worse he try's to be my best friend, helping me out n wanting me to confide in him. But I can't because the thing that's killing me is him!
Usually after a break up I would cut myself off from the ex but this time I can't because we have a child.
Please tell me this will get better. I know I haven't explained very well but my heads all over the place. I need to know that in time I won't miss him n he won't be on my mind 24/7 because I think I might be going crazy with it all
