me and DP have been together 5-6 years, things are just really rubbish and negative right now and have been for a while, I have 3 children from a past relationship and 1 child together, I just feel so bad leaving or splitting up thinking about the children our DD does adore him and looks around for him when we come home in the day when he is at work, I just feel so guilty but this relationship is really draining the life and soul out of me I’m just not myself when he is around how can I get through this what should I do
