Being comfortable does NOT include being being unhappy like that.
OP isn't even comfortable, he's just desperate and clingy. No offense meant.

A good, lasting relationship takes a FUCKLOAD more than just love, OP needs to learn that. You can NEVER build a relationship on love alone. It will only lead to misery. Love is however a vital component in a lasting relationship, but love isn't valuing your own relationship status above both of your mental healths. That's just bloody selfish, considering that if you keep at it, being this miserable, you WILL cause both of you a fuckload of pain. If not now, then a few years down the lane, maybe even a decade or more later. Trust me, it hurts A LOT more after all of that time, a lot more than now.
