I have posted on something similar before. Mid 50s, 8 or so months in. My first major relationship for many years - met through friends. It's a serious relationship for both of us but we both agree no intention to marry as we both have before.There's a real closeness between us, we talk a lot, really have a great time together, have small trips away and spend an evening in the week together and a day and night over the weekend, we chat every day, sex is great and there's a spark .After a frankly great day and a long weekend away (separately) in which we called each other every morning and evening and missed each other he became quite withdrawn and said he was grappling being in the relationship and worried, his marriage was cold and he thinks he actually finds it hard being with someone who really cares about him, he felt I was much better at taking things as they are. It makes me so sad and anxious, he doesn't want to end things and nor do I. I have dated many men and been in many relationships and I know what we have is hard to find. How do I cope ?
