Hi, first time poster. I’ve been with my fiancé for 14 years, had a bad past 2 years (all down to me) not knowing if I want to get married or have kids with her. We were at a wedding before Xmas and I knew I wasn’t happy and in the new year I told her I’ve been unhappy for a long time (she already knew I wasn’t) and I couldn’t go on any longer. Anyway, we’ve been living together during all this and 4 weeks ago she admitted (after I quizzed her) that she’s been sleeping with someone and confirmed they are an item since March just before lockdown. My world has been turned upside down since this news. I was trying to make amends when lockdown started and was having second thoughts about us splitting up. She has now told this new guy to back off while she decides what she wants (me or him basically) I’m 35 and want to have kids, the thought of her going off with this new guy is making me so low I don’t know if I could carry on. She thinks I’m only having a change of heart down to lockdown and that I was suspecting her with someone else, this partly may be true, but I don’t want to lose her. Also, although she hasn’t cheated on me, the thought this was all done in secret has destroyed me. I’m a total wreck. Please help me
