Is it time to Divorce?

I think it is time to divorce, but I would like feedback before I take this big step. I was married before and, in retrospect, regret not trying to do more to save the marriage. We have been married seven years. Here are my main issues:

Infidelity: My husband and I had a good marriage until he switched jobs and started spending every Friday and Saturday night out with his friends – gradually staying out later and later. I had evidence that he was seeing other women and when I confronted him, he said he would stop. We moved to another city where he did not have friends and so the late nights and the other women stopped. We have since moved back and while he promised not to repeat the same pattern, it only took him a couple of weeks to start up again. As before, I have concrete evidence that he is sleeping with other women (or at least trying very hard to).

Lack of Intimacy (?): Besides the cheating, since we moved back, my husband would rather spend time with his friends than with me. We do not do anything as a couple other than go out for cheap dinners (when there is nothing at home to eat). He saves the good times for his friends/other women. I sit at home almost every Friday and Saturday night while he is out. We take separate vacations and his parents (in another country) do not know I exist. His brothers and sisters do, though. We are not friends on Facebook, either because he is hiding something or he is ashamed of me.

Abusiveness: He routinely tells me that I look old, am stupid, that my chance in life is over, etc. He is younger than me, but at 47, I hardly feel like it’s time to be put out to pasture. He has a temper and I am sometimes fearful of physical harm (since we moved).
We do not fight or argue every day and before we moved back, I was relatively happy and thankful for my marriage. But with the cheating and lack of attention, I do not see why I should stay married. I am also tired of constantly having to spin the truth about my marriage in order to spare myself the humiliation of the truth. I feel that my desire to make my marriage successful has led me to accept things that I shouldn’t have.

My plan is to contact a lawyer to understand the financial implications, so that I can prepare as best I can and then ask for a divorce. I am not sure how he will feel.

What are your thoughts? Am I being too hasty? I am 47, so I do not exactly have men banging down the door, if you know what I mean.
