You can date with a lot less pressure in your 40's. No one is expecting you to get married right away. You can date that cute girl in her 20's at the gym, or meet a nice woman in her 50's at church. If you want to have kids, you can date younger. If you don't want to have kids, but don't mind parenting, there are plenty of 35+ single moms. There's also widows and divorcees in their 50's with grown children, if you don't want to parent.
