My heart hurts we came down to visit my family and my husband offered to let me and our son stay with my family if I wanted since we would be coming down again in 2 weeks for a friends wedding anyway. So he said he'd come back down for the wedding and we would all go back home together afterwards. I said ok because I really wanted that time with my family, also to let my son see them and a little time apart probably wouldn't hurt. Still I'm here bawling my eyes out because I miss him so much. I've slept next to him every night for 4 years I feel so empty without him. He's my best friend and only friend I didn't realize I'd feel way more lonely without him.
