Party with ex and his new gf

Hello,

Me and this lad was dating for nearly 2 years during the last 8 months of our relationship we broke up and then got back together and he told me while we wasn’t together he slept with someone else as we wasn’t together when it happened I let it go and we got back together.

During the last 8months of our relationship it was more casual but never of us was sleeping with anyone else I didn’t hear of him for 2 weeks which was normal as he works away a lot and I’m an independent person and don’t mither him on his where abouts as we are Botha adults.

After this 2 weeks I saw him and he was distant didn’t really think anything of it as he was going though a hard time, but I was then told it was because he had been with the girl he slept with when we was on a break even though he has called her every name under the sun not only to me but to others.

This lad is a very close friend of my best friend and we have been best friends since kids and I have a very large party to attend soon. And I got a feeling he is going to bring her to this party which would of been fine if she hadn’t openly admitted she had a problem with me because of my ex and she has told people she doesn’t like me because apparently am pretty 😂😂 and the fact she likes to create drama.
