Good Mornig EL,
Great input by SC; she is so wise.
If you feel that your boyfriend is wrong for you and know your relationship is affecting your anxiety then it may be time to end the relationship. I know that is not what you want to hear and it is only my personal opinion from my past experiences.
This can be very difficult to execute, especially if your are afraid of hurting his feelings and breaking his heart. However, dragging on a relationship that is causing you stress and anxiety and making you unhappy is not a good thing for you or for him.
Before breaking up with him, take a long hard look at your thought process and examine your true reason. Make sure your decision is truly how your feel. Whether you feel you are taking different paths in life or fight too much, be honest and open with him about your reason to terminate the relationship.
Avoid giving your boyfriend false hope about the future if you intend on breaking up permanently. This will only lead to hurt feeling and more heartache for him in the end.
Remaining in a relationship because you feel responsible for another's feelings is unhealthy and can leave you with feelings of resentment and suffocation.
This is just FYI and in no way am I telling you to leave your boyfriend for good but I am asking you to look at your reasons and to remember you must take care of yourself first.
Sending you many gentle hugs,
Kitt
