Major Problem

So major problem, these things only freaking happen to me. People wait until Im starting to be happy again and the my ex comes back into the picture.
So once the holiday has been booked a couple of hours later my ex texted me saying how he made the biggest mistake ever and that he wants me back. That he has always loved me and that he is willing to do anything to get me back.
WTF
HELP ME SOMEONE
I do still love him and my heart did skip a beat when he texted me. So obviously a part of me wants him back, But how to trust again. How do you even start to trust someone again when they were so nasty when we split up. He thinks Im spoilt (I am and I admit that) He thinks Im jealous (isnt every girl maybe she just dont admit it) He thinks Im a bitch ( Im glad of that)
I need to see a specialist to deal with my life,
Give me advice x
