Let him go Britt, you can't hold on to someone who doesn't want to be there. You can still love him, but let him be. When people can't love each other the way they require that love, those people either need to work on it together and let themselves have freedom from each other as one last loving act towards each other.
And start investing in yourself, I hear the voice of someone who doesn't believe in their own value, feels very small, very little self-worth, someone sad, heartbroken, depressed and trying to hold gallons of rushing water in the palm of your hand and you're not successful at that and it's hurting you deeply because everything you've done hasn't proven successful.
He doesn't know what he has.
He won't know what he has until it's gone.
And then at that point he will realize your value and then at that point you will be the one to choose if you want them back if you still want them back.
I'm not saying to do it now but at one point, you need some social interaction (dating) with men who will give you some attention, pump up self-esteem and make you feel good to be a woman, make you feel desirable and wanted and make you feel better about yourself. But I don't want you to base your self-esteem on that, I want you to be able to validate yourself internally instead of external validation but we all have to start somewhere.
If he doesn't value you or the relationship he has with you then let go of him, it is his loss, not yours, you tried and you can hold your head up high knowing that you did try.
