Yep, it was the same for me, teen love - didnīt last - reunited in our 40s with fullblown alcoholism on his part. And looking back, he did drink a lot too the first time around, only it didnīt seem so bad because there was a lot of partying at that age. In that time I was probably the "nerdy" odd one out because I never drank myself.
Anyway, I understand it can be extra hard to disentangle yourself from someone who was a childhood sweetheart, you feel a special connection because you knew each other in the past and you donīt want to let go of the illusion that this was actually The One.
