I thought this would happen to you because you used to mow her lawn in your undies, etc and I said so at the time but no one believed me
I'm very happy for you but also worried. Remember my ex said ILY - he said it loads, he used to stay overnights, in fact we house shared at one point and I never got him back. Does he love me? Yes, I think so, but he can't be a good husband so it's over.
Don't wish to be a wet blanket, but you're a good man and I don't want her to hurt you anymore than she did already. Just go slow and don't forget what she put you through.
