How do I tell my parents we are engaged?
To give some background my partner and I have been together for 5 years since we were in school together, we are 22 now, and were friends for a few years before. Before him I had one other sexual relationship which lasted 2 1/2 years. I was his first. We've had our ups and downs and have even broken up and both slept with someone else during this time. It didn't last very long before we were back together and we are both extremely happy together now having figured out the problems that split us up.
We've now decided to get engaged but because of the way things have been in the past my parents really don't like him (he was never violent or anything just a typical young man getting too drunk with friend etc and never cheated), to the extent that when we were having issues I didn't feel I could even ask their advice, they make it very clear they have no interest in him. Could anyone offer any advice as to how to go about telling them we have decided to get engaged? I want to cause the least upset possible and am not certain how to approach it?
Thank you in advance
