I came across pictures of ex-girlfriend of my fiance?

Honey if he's that caught up in his past to be unable to move on and share all those wonderful things that you seek with you, then your present and future with him is not going to be fulfilling. You are not wrong, and deserve a man who will adore you. Save you love for someone who is capable of reciprocating it. He's not a bad person, he's just not emotionally available at this time and who knows if he will ever get over her. Don't waste your time with him, cut yourself loose and you will find a man who will love you and treat you that way.
