You really need ground rules for your relationship. A text a day saying "I'm here, I'll text tomorrow" would help ease your fears. I'm good at faking happy with my friends, my husband has asked me never to fake happy with him. There are times when I want to run far, far away. I haven't "ran away" since October before that February. I want to run again, but I know it's from myself. 1) You can stop her from running 2) You both really need to make ground rules for your relationship to protect you and her 3) You need therapy whether she gets it or not 4) you can't force help on her, it just wont work . If you want to be there for her than do it unconditionally. When she's there enjoy it. When she's not concentrate on yourself. Slowly she may tell you why. If she is depressed than it may be because she wants you to be with someone better then her (We have rules for that too.) I wish I could help you out more.
