I don't mean to criticize (I'm doing it in the spirit of helping out the original poster, at least), but I would not recommend this.

I've been married for 9 years. In that entire time, my wife and I have kept our home lives and our work lives separate as much as possible (I'm back in school, but the same rules still apply). I mean, we talk about our work/student lives, and occasionally meet the other people's co-workers/studnets, but we never socialize with them on a regular basis. This keeps your work relationships at work and your personal relationships at home.

Of course it would be a different situation if one of us happened to be working with a good friend of ours, but that's not the case. Since your boyfriend is starting at a new job, I'm guessing both you and he have other friends outside of work, so that shouldn't be an issue.
