It's possible to want to stay married for now, and like it, and yet realize that a divorce down the road is probably the best, or likely, etc.
Read that again. You are saying that you'd rather coast along without rocking the boat and an eventual divorce is "probably the best" or the most likely outcome--and accepting that. This is the thinking people have been trying to point out to you. You're talking about everyone else being pro-divorce and urging divorce on you, but they're not. And you're talking about your stand against divorce on behalf of your children, but the stance you're taking is not against divorce. It amounts to accepting that divorce will become inevitable in exchange for keeping the peace at present and delaying that divorce.
