What ifs

So I was just being me thinking about how I want to spend the rest of my life with my partner and my mind brought up my intrusive thought of that I like boyfriends friend and then I’m like what if I end up dating this guy later in life and it’s actually not an intrusive thought and never was and I’m just in denial and actually like this guy? I don’t even wanna be with my boyfriends friend nor wanna think that I like him? I know I don’t like him but my mind makes me feel as if I do and it’s scaring me because I don’t want to like him nor feel like I will :/ I really don’t wanna be with guy I just Anna be with my boyfriend I don’t wanna think about what if I end up dating my boyfriend friend because I don’t want that to happen and it feels like it will but I don’t want it to! It feels like I’m lying to myself but I hate the thought of it so much!
