When you decide on a total commitment like marriage, you must, MUST go into it determined to never look back and say "what if..." or "if only...". If you have those thoughts now, I'd strongly reconsider your commitment plans.

In my view, what a lot of folks do not seem to realize is: marriage is trouble. You *will* have all kinds of problems. You will have conflict. The issue is not "how can I avoid these things", but "when these things occur, am I with someone who will stand with me to face these things, and/or am I willing to have patience, or sacrifice my own interests, for the overall betterment of the marriage?"

I have not been with another woman besides my wife. Certainly I had opportunities before and after we were married. But I had just reached a point where I wanted that total commitment above all else. I had no desire to look elsewhere sexually because I loved the way we had grown together sexually. And though in other areas we had some very different interests, I was fine with compromising, and even giving in (as was my wife), just because we enjoyed being with each other. In fact, I fully expected the sex to get "worse" as we got older, just because of age and other issues we had seem come up in other marriages. But I still wanted to be with her. The funny thing is how much better the sex has gotten. But I feel a big factor is my attitude of not looking back.

Now is the time to really ask and assess these tough questions. If you do not feel you can truly make that commitment, better to end things now and keep playing the field, than go into marriage half-heatedly and always wondering if the grass is greener on the other side, for you will likely end up going to that side and making things even worse. I wish you well.
