very difficult and i am on a breaking point, I guess if he doesn't give much thought into our anniversary that is my sign...I don't think you are being fair to him to make this a make or break issue. You know Aspies don't pick up on social niceties, this is something even regular guys have problems with, so what chance does he have of knowing this is important to you?
Don't get me wrong, I think you have a right to decide that life with someone with these issues is not what you want, but if you do decide to stay you need to spell out those things that are deal breakers, then learn to live with those things that are just petty annoyances.
So tell him your anniversary is coming up and that it's important to you that he do something romantic for you that shows his commiment. One good thing about Aspergers is that once you do get through to him he will probably never forget it, this is a discussion you only need to have once, lol. Yes, it takes some of the romance away, but it's can be a good example of adjustment s you can make to have a successful marriage with someone who is different.
And whatever he does, don't criticize him for it. If he thinks getting a vacuum cleaner is a romantic gesture, don't tell him otherwise. As they say, it's the thought that counts. I had an Aspie co-worker, I said something that hurt his feelings and he didn't talk to me for months.
