Everybody deserves to feel wanted. Period.
Everybody deserves to experience passionate love, to be valued, and to have their hearts full. Period. To feel what it feels like to “make love” to a person and truly feel completely whole inside. And for the sex itself to be of the flavor you ache for.
I can’t tell you what you should or shouldn’t do with your own life – only you know that. My opinion is you should talk with him first and try to make it work, before exploring other options like separation.
