Hi. Well from my point of view and similar experience I would double consider or mostly
completely eliminate option of coming back to someone who think that I need time to grow.
Maybe it’s not her who need to grow? Try to look deeply into that?

‘Major age difference’ what kind of difference we are talking about , is it 20+ , 30+ it is important to know. .
Ladies naturally mature much quicker than gents – that’s why most of us go for older guys. minimum 8y older

Best advice coming now to my mind is to live present moment future is unknown..
Which regret would you accept: something that you did – or – something you haven’t done. . This always help me make my choices. I hope it will help you to look at this from the other perspective

Good luck xxx
