I have only been married to my husband 11 months. He doesn't act interested in me at all. When I point out I need attention and compliments he says, he'll give me compliments when I look good to him and then I'll know he means it. Also; an old "flame" of his told me he came to see her just before he officially proposed to me and asked if she would ever consider marrying him-she said she said "no". We had already talked about getting married...he denies doing this and said he'd "prove it to me if he could. Well...I thought of a way. I asked him to give me copies of his debit card (she said they went out) which would show the bill..he went all around the request and when he had time today to get a copy from the bank-he didn't. I have caught him lying in the past..He shows no interest in our new house. He came to bed late last night and whispered to me; "you know I love you, don't you"....what is going on?
It seems like he really is hiding something. If you have a gut feeling something is wrong, there probably is, unless you are previously prone to paranoia in your life (which still doesn't rule it out.) In rare cases there can be a lack of libido and interest for medical reasons, but I don't think this is the case here, especially with his odd schedule (coming in late at night, doing things that he isn't tell you about).
I suppose you have already confronted him outright and asked him what's going on? Asked him blank and to the point about what he's up to?
It could be pricey, but you could hire a private investigator. I think it would be worth it. Or, you could do a little investigating on your own. Trust is something that has to be earned and he definitely hasn't earned it.
Until you do find out what exactly is going on, you have the right to withhold from him any rights he has to you as a wife. You don't want to risk STDs because you have no idea what he is doing out there. If he really loved you, he would want you, and would give you compliments no matter what you looked like.
Best of luck to you. It's going to be hard and the truth hurts, but it's the best thing for both of you.
