Couple months ago I was close on getting a divorce but we decided to work it out and my relationship is really good, but lately I have been waking up in the middle of the nights in a panic looking for my husband, I wake up in a panic feeling for the bed right next to me trying to find my husband when I don't feel him I get up turn on the lights to see if he is here, he is there but just either on the edge of the bed or maybe sometimes in the restroom. I don't know why this is happing it's like I need him next to me all the time i feel like I'm going to loose him or that I'm going to wake up one day and he is gonna leave me or won't come home from work, when I'm not with him I feel a huge separation between us, I of course googled this lol Separation Anxiety you think? I feel like that crazy girlfriend who can't let her boyfriend go
