We may be long lost twins.
The exact same thing just happened to me.
Me and my bf were totally fine and out nowhere he just started ignoring me.
Never answered my texts. Always cancelled plans. Would leave current plans early.
The anxiety it gave me was unreal. I literally would cry like once a week and was just so unhappy.
I can honestly say for the past two weeks since we broke up I haven’t been happier. I no longer worry of him going MiA and being stressed out.
I know it wasn’t my fault. It was his.
Your bf should cause you happiness not stress.
And you should feel loved and not deal with this nonsense insecurities.
You are better than him!! Your time is too precious to waste on some dude who doesn’t appreciate and love you.
Hope this could help you.
