Up until just recently, I was fine being single and dating wasn't a top priority for me. Then one day I kind of overheard my kid brother gush to my mom about a girl he had met and was dating. This unleashed a flood of emotions in me that I can barely comprehend, like jealousy and competitiveness. I raced to the only means I know to find a guy successfully and began to search online dating sites.

Why am I suddenly feeling like this? Every time my kid brother and his girlfriend hole up in his bedroom, the emotions get worse. I feel almost angry, both at myself and at him. It's not his fault by any stretch of the imagination. He's just enjoying himself with his newfound love.

Same thing happened when my mom's friend began dating his girlfriend. Mom's friend is around my age but I honestly never felt any attraction towards him. Then suddenly he has a gf and I am finding myself avoiding talking to them both as they show up at the house a fair bit. I avoid them because I just don't want to act out at them. Again it's nobodies fault here, just my stupid emotions.

Am I being possessive? How can I stop feeling this way when dating and/or sex is going on all around me? I want to feel happiness for them both. I really do. However, something within me, call it the monster that dwells within if you will, won't let me. I just want to be able to let this monster go.
