Hi Pat
From what you've said looks like you've met a gem.
I think the fact you've hooked up 5 times and speak to all the family is a great sign.
Is there no way you could rent your place in Ireland out for say 12 months and give it a go for a year so your completely confident about the future.
If not then perhaps it's just time to take the plunge after all life's far to short .
Good luck
