Im glad that I found this post.Im not married and I have only been with my boyfriend for a year and 3 months but I have the same problem and it is hard for me to trust.If I see something that doesnt mean anything I will twist it around and say he must like someone else and im always snooping to make sure that he is never lying to me.Im scared of losing him especially to someone else and getting hurt so i feel like I have to constantly make sure he isnt hiding anything from me.I too have low self esteem and I think that is part of the reason why I am the way i am.It's nice to know that im not the only one who feels this way
