I have a Brit expat friend that is 58 and his partner from Thailand is 25, he has 2 kids that are both older than her, he been with her for 7 years now.
Have another Belgian expat friend that is 62, his partner from Wales is now 30, been together for 13 years now I think as they also have a 12 year old daughter. He does have 2 kids that are in their late 20s from a previous relationship.
Have another one, he is an American expat that just turned 50 over the weekend, his partner is 27 from Philippines. They have 2 kids aged 2 and 7. He was trying to hook me up with his sister-in-law a few weeks ago LOL.
Relationships generally work based upon the work you put into it rather than things like age or race or whether you have an Oxbridge degree or not. As long as there is some compatibility and maturity then it should generally work.
Myself I will be 38 this year, have 4 kids that are aged between 20 and 3.
Recently started a relationship with someone who is 25, there certainly are issues like all relationships, we are used to rather different lifestyles as our career simply are at very different stages and what she earns in a year I make in less than a month. She will probably want her some kids in time to come, I have somewhat decided after 4 kids and as much as I love them I kind of had more than enough, oh well will cross that bridge when I get to it. There are some things that I just have absolutely no clue what the hell she is on about at times and there are stuff I do that she won't be approving off or rather she would have done it differently. However it is a fairly interesting relationship as I choose to put the work into it and to celebrate the differences rather than seeing it as a bad thing.
5 years ago when I met her while I was on conference and she on holiday, I wouldn't have ever thought we would be in a relationship and haha I didn't know she liked me either but after that gave her a chance and no regrets
Perhaps you could do the same, cross the bridge when you get to it and when you do find some differences see it as a good thing and celebrate it rather than fret about it. Perhaps you could give it a go and see if it is your thing, if it doesn't work out then you could always use it as one of the many life experiences.
