Does anyone ever feel like they are never happy in a relationship. So whatever relationship I am in I loose the spark really quickly and start thinking about an ex, but when I was with that ex I was thinking about the one before. It's like I only want what I can't have. If I can have it it's to easy. Current relationship is the best person I have ever met but once again now having these thoughts. I am so envious of people who have been married for years and are happy. I am mid 40s now so don't need to play the field. I want to settle down with this one and give him my everything but seems like my thoughts won't let me be happy
