First of all, I've got some pretty serious trust issues, especially in regards to females of my age, because of a slew of relationships from 15-19 that all ended the same way: Me getting betrayed. First, I was used as a fall-back guy like a dozen times, then used in a worse way once, so I bailed. Then, my 'best friend' decided she wanted to sleep with me. She changed her mind after a couple weeks of this, then said 'let's just be friends'. She immediately proceeded to stop being my friend at all. -.- Then, I dated one of the people I worked with, a bartender. She got upset with my personal choices, and dumped me. This hurt, but was understandable. Then, she took me back, but was trying to change me, and wanted me to keep it all a secret from my boss when
we screwed at my boss's house, on her hideabed, at the urging of my boss. Ooookay then. So, finally we break up fully, and she gets fired because of the way 'I' was behaving. (You know, being sad because I got dumped. A fairly normal reaction, I think) She gets fired, and has to move, seperating her kids from their father. This makes me feel like a fucking prick. :/ Later, I learn from various sources that the whole time this had been happening, she'd been sleeping with at least two other guys.
This marks the point at which I began actively avoiding and sabotaging any advances from women, for their sake, and for mine.
I've got pretty typical depression/self-esteem issues, and I've got them fully under control, so we won't get into that much.
I've obviously got a substance abuse problem.
I've got trust issues deeper than the Grand Canyon. I don't trust people easily. People often trust me, and think I'm great friends with them, but the fact of the matter is that I have so many people trust me and think I'm their friend, I really don't have but one or two people I trust and consider friends. Still, I don't want to let people down, even when they let me down most of the time, so I try real hard to maintain this image of 'a great friend'. This causes me a good deal of stress.
I'm sure there is more I could think of, but for now, this is enough I think.
