Do I stay in my marriage? Please help

OK, so I am married to a man basically my age. we've been married just over 2 years now but our relationship has always been rocky. I do love him but I'm not in love with him any more. I'm not attracted to him like I used to be and silly little things annoy me. My Mother keeps saying that she knows we love each other and will not listen to my concerns. I don't want to hurt him, I care for him so much but I feel so trapped. He's all I've known. we met very young and have been together 9 years. He is a great man and I hate hutting him, which is what I am doing. He tries to get close and I cant help it but push him away. I have spoke to him about separating but he wont. He says he loves me and we will get through this difficult time together. I have fallen in love with another man, he's older and it came as a surprise. He makes me feel happy and good about myself. He is fun to be around and he brings out the best in me. I am scared. I know I am going to be judged and I don't blame anyone for judging me. I've tried to turn my feelings off and I've tried to make it work with my husband but I'm hitting a brick wall. I feel I have no one I can talk to, I need someone outside the problem to give their views. Do I stay in my marriage and just get on with life, after all he can't accept a life without me. What I've done is unforgivable so do I stay and try to make him happy regardless of how I feel and walk away from the other man? There is more to this but I'm trying to type fast as this is the only time today I have the opportunity to post this.

Be honest. At the end of the day its your own happiness.Why stay in a marriage to make other people happy.No matter what you do if you stay in a marriage you will probably feel miserable as days go by. I know breaking up with your husband will hurt him so much and so does other people but soon they will realize that you are no longer happy. It will be hard for everyone to understand especially your husband but they will eventually get over with. What matter the most is yourself, to be happy, to be with someone you want to be. besides whats your option; stay with husband and feel miserable or leave and feel happy

Because youve been with your husband for so many years, there hasn't been much excitement in your relationship for so long cause its always the same old stuff happening over & over again...to you its like whats new... Now that another man besides your husband has taken an interest to you its something new & different & i won't be surprised if you end up cheating on your husband cause you can't help but to be getting "attention" from someone else. what makes it more interesting with you & the other man is that yous are having a secret flirtatious communication thing that no one knows but only you guys im assuming & that's what makes it even more interesting for you... But then your also feeling guilty at the same time why you don't want to hurt husband, he hasn't given you a reason to break up with him why your still hanging on to him & the fact that he's trying to make it work you can't help but to not put him in a position to end a relationship devastated. but at the end of the day its entirely up to you & what you want to do.
