My male best friend of almost 20 years recently told me he has feelings for me. I've had feelings for him for a long time but neither of us ever said anything because we didn't want to ruin the friendship. I also recently ended a long term relationship and he was there to help me through it all. The relationship ended and had nothing to do with my best friend. But after a while he told me about my his feelings and I told him that I had feelings for him too. We talked about us and agreed that neither of us is ready for a relationship right now but we both know there is more there. It's just not the right time for either of us to be in any relationship let alone together. So we agreed we are going to carry on as the friends we have always been and see if anything develops in time. We have spent a lot of time together and ended up fooling around a bit since we both admitted there was more than just friend feelings there but we never slept together. The problem is he is going through a really rough patch of his life at the moment and more than anything I want to be there to help him through without thinking about us as a potential couple. We used to either text or call each other almost daily but he has stopped responding to me and won't answer my calls. Before we talked about our feelings for each other I wouldn't have cared about how much I contact him and would be persistent until he answered because I know he sometimes doesn't feel like talking but he always says he appreciated that I don't give up and make him come out and talk about what's going on. He always opens up to me and we help each other through tough times but since our relationship has essentially changed in the past few months i feel like contacting him constantly when I know he is depressed and withdrawing away because he feels like no one cares, is just annoying him and I don't want him to think I'm clingy and annoying. He knows I'll be there for him no matter what happens between us but because I know what he is going through right now I know he needs lots of support. How can I continue to be there for him as his annoying best friend but not come across as being that clingy annoying girl as well?
