i am in a relationship from last 8 year and in livin from 7 year but In the last 3 years, he has had many casual relationships apart from me... I feel very insecure and at the same time I want to spend my whole life with him by marrying him... but I feel that now he is not happy with me and wants to go away from me. I love him very much and he also accepts this fact. How can this relationship be fixed?
