A friend of mine has decided after much deliberation to move in with her partner of 3 yrs.they are a great couple both lovely people although I don't know him that well.She is 43 and he is 64 and he is not a particularly young 64 just a typical older man,whereas she is young and full of life and very social.They do love each other though but he has been trying to persuade her for yrs to move in and she didn't want to but now finances have forced the issue.Do any of you have any experience of this type of age gap?What are the pros and cons?
