Why does my subconscious mind torture me?

ok so this is like the second or third time i've had a dream with a guy that i'm in love with, where he and his girlfriend are making out in front of me. last dream was i was in the street at night with my brother who is friends with him, and he was making out with his gf in front of me and i was about to burst into tears but then i saw a shotting star which i wished on that they would stop making out and as soon as i made the wish they did. later in the dream he told me that he had feelings for me too and that he didn't want to break up with his gf so maybe we could be good friends until their relationship had run it's course. the latest dream was i was really good, almost best friend's with him and his gf and friends with a bunch of other people who were friends with them and i had really strong feelings for him which i just pushed aside so that i could be friends with him. i ended up walking in on him and his gf making out and he didn't have a shirt on and they didn't even notice me so i just closed the door and walked away. in that dream he showed interest in me right in front of everyone, including his gf but i was the only one who noticed. but in every dream i've had of him making out with his gf in front of me, it hurts so bad to watch. why does my subconscious mind torture me like this? and what does it mean if anything?
