As I already said I am gay and in a relationship and I love the relationship I am in. But I keep thinking of my ex who proposed to me and how he had lied to me and cheated on me, and I keep thinking that "Well he lied to me, how do I know 'bob' (fake name) isnt lying to me right now. How do I know he isnt just saying these are his feelings?" So I really need some help and it has been nearly a whole year since that other relationship which I am glad is over and also like I said I love the relationship I am in right now, so if you could please help with advice that would be great.
