Dear Coleen: Our marriage may have reached the point of no return

dailyrecord.co.uk:

I’m a man in my early 50s and I’ve been married for 25 years. My wife was my first proper love and we had a great ­relationship for many years but now we’re different people.I’ve always been a positive person with a lot of energy for life but she has become insular and quite miserable.

We’re not close emotionally or ­physically at all any more. In fact, sex happens very rarely.I’ve got used to it now but it makes me sad.

I truly feel that our marriage has reached the point of no return and we’re living different lives. I have tried to talk to my wife about where our marriage is struggling but it always ends up in an argument and then things return to normal.

I think I have to leave because I’m not prepared to spend the rest of my life in a loveless, sexless relationship. Our two children have left home, which would make ­splitting up easier but I still feel guilty for thinking about it.Unless there’s a dramatic change from her, I don’t feel I have any choice.
