Love and friendship are living things. They change and there is lifes ebb and flow. We have to accept this as we cannot change it. I had my best friend that I knew from the age of 2. We went to school together, passed the 11+ and on to the grammar school together. Then my father got promotion and I had to leave my beloved Yorkshire and all that meant so much to me and go to Hertfordshire at 13. I was deeply unhappy about it all and especially the thought that my best friend would be friends with other people and all that we had shared would be lost. No-one seemed to have the insight or the will to help me understand what was happening and how to deal with the changes. Well you have to work at friendship as with any other relationship. I kept in touch, saw her as much as I could, wrote regularly (no phones then) . Well I am pleased to tell you she is still my longest known friendship and we have been friends now for 76 years. I moved a lot and lived abroad. I was always careful to make sure she had my new address when ever I moved. Naturally things change over the years, but we have been there for the good and bad things. I sang at her husbands funeral, she was here for me when my husband died. We have had mixed times, some years only managed to meet up once or twice for a lunch others more . But the point is we know we are there for each other and wish each other all the best in our lives. There have been the disappointments when we had hoped to get together and not been able to manage it. She was a widow for many years and is now happily married again. So in the same way I do not see her as much but we are still important to each other and know that , which is what counts. So my advice is as others say, try not to begrudge her her happiness, because if you do this will surely split you up more and be remembered. Think how you would like her to behave if it was the other way round. In practical terms one of the things you might do is something that you enjoyed but she didnt. I am a widow now and live alone. Not a lot of good things to enjoy about it , but if I want I can go out get in the car and disappear off for the day. I hate shopping and would rather sit by the sea and watch the boats or walk up in the dales. So when my husband was ill for quite a while we could not go up the dales much. So I can go as and when I like now. Have a think if there is something that you liked to do and havent done for ages and give it a go. There are many voluntary things you could do and charities are crying out for help. I did 10 years hospital car driving, read on Talking Newspapers, took disabled people for a trip out, drove the little white bus etc.Try out things for yourself and dont be too clingy. When you are able to ring or see her and tell her about your swimming or tennis or whatever ,you will both relax and then your friendship will move into another phase to enjoy. Dont lose something precious, add to it with your new hobbies. Wishing you all the best
