My toxic relationship😭

Okay so I have been in love with this boy for almost 2 years. We have dated from august 2019 to February/March 2020. I fell in love with him and I still do.. let me explain I lil story before, about us... so I was born in Switzerland, and now I live in Italy. I arrived here in 2010. My “bf” is from Ghana and arrived here in 2016. Last year, we found out that the guy who has worked on our house in 2010, when we arrived in Italy, was the dad of my bf. I was 12 years back then, and his kids still lived in Ghana. We had extra clothes so we gave him many to send them to his kids in Ghana. All this in 2010. Of course my bf was one of the kids who received our clothes. 7 years later I meet him through a friend we had in common, and in 2019 me and him started to date, without knowing and remembering who our families were, I didn’t remember his dad.. but last year, my mum saw a picture of my bf’s dad because she never saw him before and she recognized him immediately.. saying this was the guy who worked on our house and the guy we sent away our clothes to, for his kids. We were really shocked and, I don’t even know if to call this a simple coincidence. Anyway, things got pretty bad for us because, my bf got back with his ex girlfriend without telling me. I only found out about this when she left him again and he was heartbroken, so I forgave him.. he was in pain. After that, he said he couldn’t date me anymore because he wasn’t ready to date anymore. It was hard for me, very hard but I accepted it again. So since then and still now, we haven’t stopped sleeping together, maybe for the bond that connects us or I don’t know.. but now I have a problem, he still says he doesn’t wanna date anyone, after a year that has passed, but I know he is texting a new girl, I know with all my heart he is lying to me and he tells me he never met her. But I saw one of her text with him saying “good morning my king” with a heart. Yesterday he told me he is confused and wants to find another girl but doesn’t wanna lose me. Guys I’m lost. I don’t know what to do. I know he likes her and I know they chat a lot, I’ve seen it. I don’t know what they talk about or anything but, I can see they are close. Why doesn’t he want to lose me if he does that?? Why does he want another girl? If he says he’s not ready to date to me?? I am so confused and so sad. Please I need to know what should I do :( what are your opinions? I always thought we had a strong bond and everything, but I see he’s always looking for something else, I’ve done everything for him, and I could do everything to want to see him happy again but, now he seem even more distant.. it’s like he doesn’t really care anymore. But how can someone not care anymore like that? I even caught him going to her house but he denies and tells me he’s always truthful to me.. I know he is lying tho. I just know him too much. Please help me I am lost 😞
