Offended girlfriend :(

Wathene
My boyfriend of almost 5 years proposed today 😄crazy excited thought it never happen. I text our girlfriend to let her know because I was telling everyone and didn't want to leave her out. Now she's up set he didn't wait for her to be there with us. It breaks my heart that we hurt her feelings but at the same time I'm kind of up set she'd even take the chance of ruining this for me. I don't know what I'm supposed to do I really didn't think I'd get a negative reaction from her 😢
