Cousin texted me that she got engaged while I was on a date

So my boyfriend and me were supposed to be going to an amusement park and spending the night out of town together. We ended up going to the state aquarium and came back to his place to spend the night together. After we got back my cousin who is like a second mom to me texted me this.

Her boyfriend and her have only been together a few months, so I really didn’t know what to say. This will be her fifth marriage and a lot of the family thinks that they may be rushing things.

Update: they want to get married next month. I’d be totally supportive and happy if they would both stop pushing me with my relationship. My boyfriend and I have decided to wait until we are older and I have finished my bachelors degree before we even talk about marriage. We’ve barely even talked about moving in together. Now they are asking me if the two of us want to go to Germany with them next summer.
