Empathizing in a personal way here.... I haven't even held hands yet with my FarawaySweetie, nor kissed her, nor gazed into her eyes. What I have done is exchanged a lot of emails--and I mean a LOT. And talked long hours on the phone. So I understand the challenge of patience and waiting. Only, in my case, patience and waiting are about (a) she's very recently divorced and still grieving the end of that relationship (b) she lives twelve hundred miles from me, and I from her.
Eight months? Good grief, I'd pull my hair out after a certain duration.
Your gal's husband sounds a bit too freaked out about his gal's loving another man, if you ask me. Will he EVER allow her and you the freedom to love whom you love without constraint? Consider this question carefully.
