Throwaway acc just in case. I'm pretty confused. He is not technically my father in law because I'm not married yet, it was just easy on the title. I'm still working on my English, sorry in advance.

For starters, I don't like him. I (23F) have been officially dating my boyfriend (22M) for almost two years although we've been together for longer. I currently live in the US with my boyfriend but before that I used to live in another country, we met there and would be together whenever he travelled, I met his family in person this year but had seen them on FaceTime before. His parents are divorced, his dad is recently divorced from his second wife. He is not much older than us, he is in his early 40's.

I always got along with everyone in his family, I don't have a dad so he was like a second dad to me, always really nice, taking care of me. My boyfriend is extremely close to him, he always says he wishes to be at least half as great as his dad is, he admires him so much. A few days ago we were staying at his dad's house and my boyfriend had gone on his morning walk, I sometimes go but I stayed because I wasn't feeling okay. His dad came to our room and gave me a mug of tea for the pain then sat on the bed to talk to me, I didn't think anything of it since to me it was him just taking care of me.

Well, long story short, he confessed his feelings for me. He has liked me since we met this year, he thinks I'm beautiful and that he can make me happy if I give him a chance, he told me not to say anything to anyone. I rejected him, obviously, although I was pretty shocked. I made it clear that I'm in love with my boyfriend and then I used me not feeling okay as an excuse for him to go so I could "go to sleep" although it was the morning and I was so confused I couldn't sleep. I spent the day "resting" in the room and we left that afternoon, my boyfriend has noticed that something is wrong but I keep making up excuses. I don't know what to do.

My boyfriend and his dad are so close, they have a great bond. If I had a son I would want his relationship with his dad to be as good as my boyfriend and his is, that's how good it is. I guess I should have suspected. He would look at me often, some time ago I noticed that I had a few "🔥" reactions from him on Instagram from before we met, at the time I didn't think much of it since I work with social media so I have a huge following and you know, men are men. I guess I should have thought of it now and I feel so dumb.

Also his second (ex) wife is Asian like me and he would sometimes talk about how beautiful Asian girls are but I also hear that often since I moved here, there's lots of situations like that now that I look back. Lots. I don't know, I feel SO stupid now that I think about it. I am super friendly (I think that's the word) and people often think I'm flirting. I don't know what to do, how do I tell my boyfriend? Do I tell him? His dad has not been bothering me nor did he say or try something after confessing so maybe that was it? Maybe I'm overthinking? I don't want to ruin their relationship. What am I supposed to do? Maybe he has noticed? But if he didn't? What do I do????
