Have an adventure together. Have sex in a different place. Explore the endless possibilities.
Sounds like you two are just bored.

I left the faith before my husband. He wasn't pleased. I repeatedly asked him to consider the possibilities of the things I was grappling with. He did and eventually left the faith too but it was a rough 3 years

YES!
Familiarity can breed contempt!
People do change and grow apart with time, yet can grow together also!
Couples seem to want different things at differnet times!
It is almost impossible to matchup those needs and wants 100%!
Physical, sexual, emotional needs and wants also change with time, our inclinations, are without any clear and present reason or cause!
Sometimes we hold on because it seems safe, wholesome, and easy to content with!
Life is always experimental and ever changing!
There is no easy answers to living your life!
Only depends how much you want and like your present situation, to stay and hold on!

Have you told your spouse this? Communication is key, and if you suffer in silence, it's kind of your fault

Hi that is very sad ,I know in my case many years ago ,my husband and I grew apart ,in every way ,there was nothing left ,I still loved him ,but we became strangers,,things happen that you don't expect,feelings of sadness loneliness,,are all a part of being human ,,I do hope yr feeling of loneliness passes ,for you ,

Hard to say from just one sentence, but you are concerning me... The way you phrased that suggests that this loneliness is a common thing. Is your marriage having issues? If so, have you talked to your spouse about it? a counselor? friends/family?

I think this forum may relieve some of the loneliness, good conversation. Your spouse provides many of your needs, maybe here can provide companionship. Similar minds and all.

Are you lonely in your marriage and how so? Please elaborate.
