Im really really struggling....

My boyfriend is a phenomenal man. He does everything he possibility can to make life together easy. We are happy and we have a great relationship.... but lately my insecurities have been getting the best of me. He's not an affectionate person... physically or verbally. I want so bad for him to just tell me I'm beautiful and he won't... it's to the point I honestly don't feel the least bit attractive nor do I feel like he's attracted to me. He's beautiful and perfect and I tell him that all the time... and may get a you too babe or a thanks back... I'm breaking down... any advice???
