I think from all that you have shared that it is obvious that you are not in love with your H. You are right to face this situation and not shy away from it. Have you talked to your H about things? Does he know how you truly feel? I suspect he will not let you go willingly anyway.

Don't be dishonest. Work through your feelings and check and double check there are no underlying issues which you may well just take into another relationship should you and your H divorce. From my perspective it seems like you married the wrong guy. DO NOT even consider starting a family.

This is just my opinion and I am in no way an expert but I was/am in your position. All I can say is if you have tried EVERYTHING (individual and marriage counseling included) but it has failed then it is better to go your separate ways.
