Some men just dont like a very clingy and over too dependent women but i assumed you already have figured what kind of husband you have for you're already married to him.
If he said he's not cheating on you then believe him. That's the best think you can do for the moment and dont be too demanding on him and give him all the space he wants. Then you can have more time for yourself...isnt that great? Make the present situation work for you, not against you (talking about the distance).
Bear in mind that he wont make any of the effort if he doesnt care.
Think positively and dont aggravate the situations.
You can never depend your happiness to other ppl. But though it does helps if theyre in accordance to our will...but life doesnt work that way...everyone is different..
Cheer up.
