Hi
Im a girl and I have a best friend who is a guy.. We are very close and have been friends for over 8years now.. But I'm scared my jelousy and insecurity is pushing him away.. I question him about every girl that contacts him etc and he flips out but then forgives me and says don't do it again, he calls me stuff like pysco and hypocrite in anger, he is really busy working but I have the tendency to annoy him all the time because I'm really scared of I might loose him, I need him he means the world to me he's my rock and I know I'm his to, I keep thinking he's ganna replace me, he constantly reassures me but why am I still like this, I feel like he doesn't want to know me etc.. Why am I like this and how do I deal with it.. Coz I can't do it anymore please help me..

You are way too dependent on this guy meeting your needs. Basically, no matter what, all the reassurance in the world is never going to be enough for you because people like this are so insecure that they have a hole inside themselves that can never be filled. If he wants to be with you, is with you, and is giving you no reason not to trust him TRUST HIM. Otherwise you will suffocate him and drive him away. If you have a balloon and you want to keep it, the harder you tryu to hold on, it eventually will pop and he will eventually be tired of trying to boost yourself esteem. You need to feel good about yourself. Guys are attracted to self confidence and neediness is not attractive. There will ALWAYS be someone BETTER than you but you have to remember that you are the special one that caught his eye and if you are torturing him with questions all the time, he will tire of that. You need to find things to do while he is at work and develop your own interests so you have things to talk about. Your problem is that you don't love yourself so you think he has no reason to love you. If you ssaw the good qualties in yourself, they would shine.

How old are you both?

You my dear sound really obsessive and perhaps even a little psycho in his eyes, if you think he's going to replace you if you keep acting the way you are he will. Everyone needs there own space and you calling and questioning him all the time is not a solid foundation to build a true relationship on,perhaps you should get a hobby to occupy your time when he is not around,
Blessings in love and light

You are way tooo dependent on him. You are expecting him to fulfill a void that is only meant for God to fill. No person on earth can show you the love you really need. 1 Cor 13 says that love is not "Self Seeking". Your motive as to why you desire this guy in a more than a friend type of way is because the Love of the Father has not been perfected in you. Jesus thinks you beautiful, and awesome. He has someone who will love you unconditionally and you won't have to chase them down. The Lord will "Perfect" all things that concern you, including bringing you a husband. YOU ARE MORE, YOU ARE BEAUTIFUL, YOU ARE LOVED. <3
