I am a man. Women need to satisfy their partners, men need to satisfy their partners. Men have to satisfy themselves and their lives, and so do women. If you truly love him then don't throw the marriage away. Right now he has all the power because he is willing to cheat and is not afraid of losing you. Yes he did cheat already, I promise. By the time I found texts like these my woman of seven years had cheated on me multiple times, and vice versa when she read some of my messages. You need to take the power back and get him interested but also get under his skin. Start going to the gym, start really taking care of yourself. Start going out alone and don't tell him where. Flirt with other guys, but dont do anything. Subtly flirt with guys in front of him, after doing this I promise he will make love to you like he never has before. You aren't doing this to hurt him but to show him you will stand up for yourself and that you have options just like he does. It shows what he is doing will not effect you negatively. As much as cheating hurts it can spark a love life like nothing else. My SO and I of seven years have cheated on each other like 10+ times individually, most of this stemmed from substance abuse issues. Still we were having sex four times a day everyday and it hasn't ceased. Sex is a good way to channel that hurt and pain into something. Most men have super high labidos, you have to put yourself in his shoes. He is unsatisfied sexually and is around another woman often, obviously something is going to happen. I promise once you take charge and start changing things about yourself he will be notice and start giving you more attention. Take yoga, go to the gym, library whatever. Change mentally and physically. He has the power and you need to develop some for yourself, it will surprise him and make him start thinking, worrying, and desiring. Cheating is immoral but it stems from not being satisfied, its also like a high, it clouds you immensely. Disrupt his immoral foggy haze. There are a million approaches you could take, and we all know too many women in this situation left their husbands and are still miserable to this day, wallowing in self pity, my mother included. If she had followed my advice she would still happily be with my father and I know it. He couldn't get over the fact she was hate filled and spiteful and yet wouldn't do a damn thing to change this, like c'mon obviously he is going to continue cheating if you are stagnant and as sexy and mysterious as a rock.
