Hi Chrys,
The first thing to remember is that people change. We are, all of us, changing and evolving as individuals on our journey through life. (Hopefully towards greater wisdom and acceptance – but I can’t guarantee that!)

I’ve noticed with friends around me that when people split up, the 2 people that spilt up aren’t the 2 people who get together in the first place; either 1 or both of them have changed in the intervening period.
It sounds to me like you had a very strong friendship with this guy but that a more intimate, full-time relationship didn’t work out. And the reason that it didn’t work out is that it didn’t work out. No guilt. No blame. Sometimes it just happens.
Your feeling sad or angry or swallowed up isn’t going to change how this guy feels about you. Experiment: Next time you feel suddenly sad or angry ask yourself what effect this has had on him. Answer: None at all.

What are you going to do about it? Try this – after you finish reading this go and find a mirror. Stand in front of it and send yourself love and acceptance. Think of all your achievements, the help and encouragement you’ve given, the compliments you’ve received. Send yourself that love because you know that you’re worth it.
And if you’re in any doubt, know that complete strangers who email you know that you’re worth it.

If this works for you I recommend that you do it regularly. There are 2 reasons for this:
1. It’s a better alternative to feeling sad or angry

2. It will start a light inside you that others outside will notice and recognise and find attractive
Hope this helps.
Take it easy,
Tim.
