All of the older men, who lost their wives, in my family have done that. Statistics show that older men who become widowed either re-marry quickly and continue to live happy healthy lives, or start to withdraw from life and die fairly quickly.
My aunt, who is in her 60s and has been divorced (after two marriages during which each husband cheated on her) since her 30s, has seen many situations of a wife dying and has watched what the men do. In HER experience, watching it from the outside, the men either get married very very quickly, die very quickly, or, in her words, "get weird".
But I do hold people to a standard of decency requring them to treat their living family and their dead spouse with respect. IMO, moving on that quickly (2 months) is disrespectful to the deceased and insensitive to the needs of living children. I am tired of people getting remarried asap and getting so angry with their adult children who are not ready to 'move on' that they cut all ties with the children and grandchildren because they're not ready to throw a ticker tape parade. I have also seen many many people come to regret moving so quickly (including my FIL) to think it's a wise idea.
Yes!
My stepdad was going to the Singles bible study groups within 2 months or so after my mom's death. I understand he didn't want to go to the couples study (though, gosh, way to abandon your friends!), but he did start meeting women immediately. He was a good catch and he was even being checked out by the women running the post-funeral reception thing at his church, and he quickly narrowed it down to 2 women. Then got to know them on a friend's level, had a date with his final choice, proposed after that, and got married a month later. 10 days before the 3rd anniversary of my mom's death.
It hurt me deeply. I never said anything, though, b/c frankly he wasn't worth the argument, and his answers to unpopular decisions in his life were that he had prayed about them and got his answer so he knew he was doing the right thing. Always convenient that his "answer" was always the one that he would enjoy the most! He hurt me horribly, he hurt my aunt deeply as well (they were STEP cousins after grandparents on both side married each other, which is how my mom was his young teen-hood sweetheart), he caused grief everywhere from the decision, but HE got to marry (and therefore live as a married couple) quickly, and that was all that was important to him.
Sometimes I feel for him, having to grieve while inside a new marriage (even now, 9 years later, I realize that I had almost no business starting my relationship with now-hubby only 7 months out from the death of my mother, for instance...I can't imagine if it was a husband that had died!), but he made that choice!
