I dont know if this is anxiety or what it is but I cant seem to trust my gf. I know deep inside I do trust het but cant help but wonder what if she could or what if she did. Its eating me up inside?

Insecurities about our own worth are very often reasons for variety of reactions that all come under the same umbrella - jealousy. It cuts deep and it is painful. We all have it and we all deal with that feeling in a different way. When you are jealous most of the time it means that you are not comfortable in your own skin. People who love themselves, people who are busy with their own lives and work on their own improvements daily do not have time to be jealous. Trusting means being open and loving and accepting and being secure in your own skin. If you can not trust your significant other usually it means that certain things about our own attitudes about ourselves should improve, or significant other should not be a significant other.

Trust is key in a relationship. Try being open with how you feel with her, tell her what's on your mind. Reassurance gives you peace of mind and it will give her insight on how you feel, It's okay to feel this way but it's important to remember that you can't let this eat you up! Talk with her, and maybe she will say the things you've needed to hear in order to be secure in your relationship! IT's a hard process, but I know you can do it! Theres nothing to it. IT will be okay, know it!
