Oh crap...I just posted a heap of stuff and it didn't save.
O.K...can't go over everything I just wrote so here is a brief version...
I'm going to leave X alone in bringing him up all the time. There are heaps of nuances that just aren't worth going into. All I can say is that don't underestimate the power of fear. I don't know whether he is fearful of me or not: my guess is that he's built up a character analysis of me that I'll bet makes me out to be some terrifying demon. I might be wrong, but I also think that X uses fear to get results. If he does, then it's because he is focused on fear. I don't know, and honestly - I'm getting tired of trying to work him out. All I know is what I see. I wish I could help him overcome whatever the problem is, but he won't let me. I'll bet if I cuddled him it would all disappear. Problem is...how to get him to do that? I don't think he's afraid of me as such...it's more about what I represent. Don't know...I just wish he'd hurry up and get over it!
I'll just share this though... in 2004, I went out with a CEO of a multinational company. This guy had offices all over the country and overseas. He was incredibly smart, scholastic, great social skills, HEAPS of money, but guess what? Like many men...was afraid of intimacy. Mind you, he could never make me feel like X made me feel. I always compared, and this guy just didn't really do it for me. Maybe this had an impact, but he told me once that my intuition scared him. I found that amazing. It's all about simply being able to read emotions, know your own, and have courage. So, I let him go after 9 months. It might've been different if there was chemistry but there actually wasn't. Point is...he was fearful!
O.K...now your story #2 - Jealousy
Yes, it kills! Jealousy can rip you apart and create self defeating behaviour. If you get jealous - then you're back to focusing on FEAR. Make no mistake, fear KILLS !! Can't say it enough. I have a couple of male friends, one is married. I wouldn't even ALMOST think about anything other than friendship with either one. I've never been with anyone that has caused me to be jealous. The only one that has the power to make me jealous is X. AND he does. I hate it

. Anyway...jealousy can be contained depending on how you treat your partner. It's all based on how you treat her and how you feel about her. This will level off as you get older. At your age, it'll be an issue for sure. It usually is in your teens. Should you be worried? Only if it gets out of hand to the point of ridiculousness. Her reaction is perfectly normal. Again, communication is the key. The more you two communicate, the better contained this will become. Don't forget, at your age, you don't have enough relationship experience to feel comfortable with 'perceived threats' (for one of a better term). Relationships are all about learning to communicate, learning to trust, be sensitive, develop awareness and respect (for self and the other), it's about many, many things. You're only starting out here, so start talking with each other to find out why she is jealous. Then, go from there. Certainly don't throw away any of your female friends, but talk about the issue so you can manage it.
Hope this helps. Crap...my last post was better, but never mind. God, it's not so brief after all. I type over 80 wpm, so it doesn't take long
