Likely, you're experiencing reactions. Something about what he says or does reminds you inappropriately of something in your past that you didn't like. This could be a rude behavior from someone, all the way up to serious trauma of some sort. What you need to do is every time you sense him irritating you, stop and think of how you feel, what it is that made you feel this way, and see if that's a rational thought. If it's not then you might be filtering the information. If that's the case, try to think about what it is in your past that this reminds you. It'll probably not work the first bunch of times you do it but keep at it. Eventually things will begin to slide and work again.
Just chill. Stop hounding him every time you have an emotion. Stop clinging and just trust.
trust him or dump him.
it's no good for either of you if you don't trust him.
Jealousy is a very common problem in relationships. So be comforted with the fact that you're not alone. :)
You can start just by taking little steps. When he hangs out with other people, resist the urge to text him or keep tabs on him. He'll appreciate that.
When you see him talking to other girls, remind yourself that he chose you.
Build up your own life with things that please and interest you. This will increase your self-confidence and naturally insecurity will diminish.
jealously is a wasted emotion ...Be better then that..
You're going to have to dig deeper and take a deep breath before you react. Also, when I was your age, I was a lot more impulsive and moody than I am now. Some of it may just be due to age and hormones. Keep telling yourself not to sweat the small stuff.
Well try to trust and love him more..buy him a gift go for a walk together and talk.
