geesse tree, i'm so sorry your feeling like this, it must feel really strange for you, no wonder your soooo confused, he cares for you, & its so obvious he means alot to you

he's told you he has a good support network, but you cannot put your own needs before his, have you told him this, does he know exactly how you feel, if not you need to tell him, you need to let all this worry out, if he isnt already, he will be touched by your concern, & he will help you

the last thing he would want is for your progress to be hampered, due to something to do with him, that would only make him feel worse, be totally honest with him, you can only work through this together

please dont shut down, try to look at it you being strong for both of you
