I'm married for 2 years now, I'm 30 and my husband is 38, my husband stopped having intimate relation with me for a year now,making a lot of excuses,like that we are having a lot of fights,he is chatting online always from his work and I'm afraid that this affected our marriage, when I talked to him, he denied his deeds and told me I'm just jealous, what can I do??

Time to make it clear that while he may be happy, you are not and that not working with you to solve this is not acceptable. I would politely insist it be talked about until you both come to some agreement as to what the actual problem is. If you cannot come to an agreement on that, I would recommend you visit a marriage counselor. Have one picked out already so there is a kind of seriousness of intent here. If he won't accompany you, go alone. Its really a matter of follow through and solving it one way or the other, with or without him-- sad to say. Its just not possible to solve it alone so seek his help and if that is not forthcoming, seek professional help.
