Holidays are hard. And really, staying in contact with him is making the duration of your hurt even longer.
Someone just said in another forum, Short Term Pain for Long Term Gain.....and that is so true. Six months is not a lot of time in the grand scheme of things. The true healing will come when you go no contact with him and have no idea what he is thinking, doing, etc. Then YOU can heal, it 's not about him anymore.
Hugs to you.
