I have been with my girlfriend for just over 5 months , a couple of weeks ago she went to a wedding with her ex boyfriend which involved a two night stay , I had to accept this because it was arranged before we met , now she tells me they are planning a weekend away with friends from the weather, I told her this is unreasonable, total disrespect to me and it should be me going not her ex … am I right in saying this because she said it’s her and her exes friends so I’m not invited .. need some advice on how to tackle this
Thanks
