Its my Partners Birthday and I know that he feels genuinely down as he tells me its not worth celebrating due to the loss of his mum a few years ago. He announced yesterday that he was going to get away from it all and off to the coast just to chill. I did suggest I come with him for company but said we would just fall out. I've not heard from him despite wishing him a Happy Birthday text earlier. This is making me rather paranoid to be honest. As awful as it sounds My immediate gut feeling is that he is seeing someone else as he wont resond to my calls and texts. I want to give him the space but at the same time I feel terrible about it. Am I being unreasonable here ?
