@NoSaint,
Quote:My husband actually wants me to do something out of the ordinary as an apology, this is why I'm asking.
Sorry, I didn't realise you had discussed this with your husband. Quite honestly, this is a very strange question. If you are truly sorry and he accepts that, then no gift is needed. If he does not forgive you, then no gift in the world will put that right, unless he is a jerk. Beware letting yourself be guilt-tripped by this guy. What can we say? A phone? A car? A yacht? A cruise? A shirt and necktie set? Some nice shoes? A wristwatch? If he (or both of you) think that relationship damage can be mended by spending money, then, as you suggest, I do find this approach deeply inappropriate.
[Edit] You want my opinion? After 9 months he is shitting you. You should walk away from this dweeb.
