Dating To Relating Torrent

Always had some awkwardness with my parents on dating. Now my boyfriend is visiting. How to break it to them?
A man whom I have known for a long time and I attend college together. After years, we’ve finally gotten involved and it’s the happiest, most fulfilling relationship I’ve been in. Although he’s intelligent, funny, and makes me feel good about myself, I’ve always been ashamed of anything dating-related in front of my parents, especially with their speculation on my relationships with others– accusing me of being involved with any male I happen to spend time with. My boyfriend is passing through my home state and where I’m presently working in order to drop his brother at a summer program and I’d like to welcome him to stay over a night or two, as well as a dinner. How do I best break to my parents that I’m dating someone without facing a torrent of interrogation?
Just to clarify: I am a college student that attends school in my boyfriend’s home state. I have returned home for the summer holidays to work.
This weekend I am going back to visit some old friends I haven’t seen in months. This will be the first time that I go back since I have met and started daing my gf. I know that they are going to have a million questions about her (she is not coming with me) and I will gladly answer all of them because I love talking about my gf. You care about your bf and he cares about you so you shoould care about what your parents are going to say. The relationship is between you and him not you, him and your parents. Give them a chance to meet him and see that he is a great guy and treats you well and they can like him too. Warn your parents that you want to invite him and that you would like for him to be able to stay the night then you can absorb the unending questions and then he can come in and finish up the remaining questions when he gets there.
