Search Results: having an affair

I found my boyfriend of 2 years has been cheating on me for 4 months today through his lover. So my boyfriend went for work placement abroad for 1 year and 7 months ago he met this girl at work and began flirting with her and asking her out but she said no because she knew about me. However, 4 months ago they began dating and having sex 4-5 times a week, he would stay at her place and also when they had sex he would finish in her because apparently she was trying to get pregnant from him. He also bought her some gifts and took her out to expensive restaurants. He returned home due to the virus, but he has been in contact with her for the past 2 weeks until she broke up with him and realised she passed him chlamydia. I am totally devastated I don’t know what to do, he claims he’s been having an affair with her due to the long distance but then why have sex with her and finish inside her, trying to get her pregnant? He keeps telling me it was purely sexual, but the girls also met his mother through FaceTime couple of times and he introduced her to his mum. He said he will never get back with her, but he’s due to return to the UK for work once the virus is over. I feel absolutely devastated and I don’t know if I should forgive him... while he was away he contacted me every single day and called me but I realised he went cold since he met her... what shall I do?
