Since the demise of my marriage, 3 years ago, I've been in a relationship with a man 15 years younger than me. It's had all the cliched advantages of a relationship with a much younger man, and all the probably less talked about disadvantages. I am deeply in love with him, and we've been through a great deal together. We also work together - it's not all the time, but it's a significant part of both of our working/creative lives.
For the first two years of our relationship, he was extremely possessive and needy - he was going through some mental health issues at the time - and I chose to stand by him even though he was very difficult. He's now fulfilled, happy, and content, and I'm delighted. However, I also feel that I am slowly losing him, as is perhaps inevitable given the age gap - he needs me less, has more of his own interests, and is frequently out. Normally I would relish this as a healthy relationship, but I spend a great deal of time absolutely terrified that this night is going to be the one where he meets someone else, more compatible agewise. We have both agreed that our relationship is not for the long haul - he wants kids, and I, at 40 and with two teenaged kids, am definitely not interested in having more.
So - do I take matters into my own hands and preemptively end things with him to avoid getting hurt - or do I take things day by day and just accept that it's not going to last forever? I find myself very sad a lot of the time, and that's neither cool, nor attractive to him - I can feel him getting antsy because of it, which is unfair but understandable.
