I need some advice. I have been very stupid and got myself into a situation. I don't know what to do. I've been married to my second husband for 25 years. For the last 3 years we've been at home together due to his retirement due to ill health and my retirement. Just before lockdown I answered a post on Facebook and someone responded to my reply. It was a boyfriend I had over 50 years ago. He is now 77, divorced after 47 years of marriage and not in good health. He started messaging me and begged me to visit him. I told him it was difficult and he said my hubby should let me have some freedom. He has been a bit nasty in a couple of messages about my weight, smoking and other things. My friend said I should block him. He is always on about the different women he's had but I don't believe some of it. We message every day but it gets a bit much. I have met up with him a couple of times. Everytime I try to cut down on the messaging he sends me a message to say I'm scaring him. He thinks that if anything happens to my husband I will run into his arms. He gives me the guilt trip if I broke off my contact that's him finished. I don't want any type of relationship with him whether I'm married or widowed.
