Jealousy causing serious problems?

first off its great to know that you can admit to blowing this out of proportion...i can kind of see where your coming from suspecting something is going on..no man wants another man spending time with his family...even if it is a male cousin..however you have heard it from you wife, mom, and sister that nothing is going on and your acting ridiculous...pushing you cousin away isn't going to fix anything...it might even make matters worse...so why dont you sit down and have a talk with him..let him know exactly how you feel dont leave anything out...if he is this cheerful fun loving person you say he is..everything should be taken care of with a talk..dont put him out of your families life because your having a break down right now....be a man and face him ...communication is the best way to resolve any situation...with out that we have nothing..
