Prepared to be flamed here and not looking for sympathy. Me and DH been together nearly 25 years since I was 17, him 21. DH discovered few messages on my phone last night between me and old friend/work colleague. He messaged him and then blocked him on my phone, dont know what he said to him. Me and this friend have messaged on and off since start of pandemic, sometimes about life's problems, other times not so innocent. Did go a few months without messaging. Life not been easy the last 18 months. We have 3 dds, eldest who's 13 suffers from anxiety and is currently getting help for self harming and suicidal thoughts. She and DH have a strained relationship at times, he can't accept she is growing up, questioning her sexuality and pushing the boundaries as teens do.My DM suffered a stroke last year then passed away suddenly 5 weeks ago. I don't know why I've behaved like this, knowing it's wrong. Feel I have lost the plot tbh, may have been escapism from reality of lockdowns, my mum being ill and then dying. I just look in the mirror and the person I see isn't me.I suffer from bulimia which has been worse this last year but I've refused to seek help for, have dropped 2 dress sizes. I have apologised and DH wants to move on but I feel awful and now see what a terrible and selfish wife and mum I am
