I've been dating my boyfriend for 4 months and recently realised my feelings had developed. I have fallen in love. With this, I have started missing him so bloody much. From a few hours after I leave him until the next time I see him (usually a few days), I really miss him. He's all I think about and it's doing my head in. Never felt like this before and I've had a few long term relationships. It's crazy! Is it normal?
