My boyfriend (41) of 2 years is married (28f)

I (28f) have been dating my bf for 2 years and last week found out that he is married. His wife (41f) has been abroad for the last 3 years in a different continent and they have been separated for 8 years. I am so confused and lost and don't even know where to begin with this. <br><br>My bf and I have been living together for over a year now. We met at work and he told me he was separated from his wife when we first started chatting (he didn't tell me anything about her being abroad). He said they hadn't been speaking for years, aside from their daughter (15f), they have absolutely 0 contact or communication. They each cover their own living expenses and he told me he covers 50% of the mortgage for their marital home (they bought it together). He told me he thinks she had been in another relationship for a few years in her new country. I believed him bc he seemed so genuine and we were just talking at the time and nothing more. I only found out about them still being married bc his daughter (my boyfriend's) posted about her parents still being married and in love in a comment of a post they all follow. Once I started digging I found more posts from both his wife and daughter that they are still in contact. They call each other 'my love' and are still very much in love. <br><br>My bf and I went on holidays abroad last year, but only within Europe, and he said it was his first holiday in 10 years. He told me that his wife was the one who always wanted to travel and explore the world and she did it a lot before they got married. After they had their daughter she stopped and stayed at home. But when their daughter turned 10 she left the country (not Europe) to work and took their daughter with her. The plan was to only stay there for 2 years but she ended up staying and my bf decided to stay in their home country for work commitments. He told me how much he missed them in the first few years and how difficult it was for them. <br><br>Whenever I asked him about his wife past he would tell me how much he loved her and respects her and how she is a great mother and person. He told me that the reason they separated was that he found out she was having an affair with someone at work. I was so confused as to why he would speak so highly of her if she did that but he said it was water under the bridge and he forgave her and didn't want to talk badly about the mother of his daughter. <br><br>I feel like my whole world has been turned upside down. My parents are divorcing after 35 years of marriage bc my dad cheated on my mum multiple times. I told my bf about it when we first started going out and he hugged me and told me how sorry he was for me and that he would never do that to me or hurt me. <br><br>Now I feel like I've been living a lie. We have been on holidays together, I met his family and they met me, I met his daughter and she has met me. I don't understand why he told me he was separated when he is actually married. What does separated even mean if they are still married? I feel like such an idiot. <br><br>His wife has been making public posts and stories in her social media saying how much she loves and misses her husband and they are each other's soulmates and meant to be together. My bf follows her and sometimes even likes some of her posts.<br><br>I am at a loss for what to do. I confronted him about it and he told me he didn't want to tell me bc he was afraid of losing me and he was planning on divorcing her this year. He said he hasn't spoken to her in years aside from their daughter. The last direct contact he had with her was over the phone 5 years ago. They only communicate through their daughter or writing each other letters (he told me he writes her a letter a day). I don't know what to believe. I don't know if I should pack my bags and leave and never see him again. I don't know if I want to stay with him. I feel like I've been betrayed and lied to in such a huge way. I was planning on proposing to him this year. <br><br>**TLDR:** I discovered my bf of 2 years is actually married with a wife and daughter abroad. They have been separated for years but there is evidence that he might still be in love with his wife or still communicating with her.
