Ok can I vent?

Sarai • A mother of two amazing children. Miscarried at 20 weeks with miss Avonlea. Our heavenly angel
I had a boyfriend I was moving across the country for. I was head over hills for. Things happened and his dad was in a horrible accident. He went back home and cut me off. This was six months ago. I am now madly in love and getting married. I hear from the ex again. And we get along so well. We caught up since I had forgiven him for hurting me. We talk and talk and just about life and kids. Well. He now wants to meet this weekend behind my fiances back. This is why it's hard. I have never felt like this about anyone but him. It still makes my heart beat fast. I am so shocked and I dunno what to do.  What if things go too well? And we decide to keep going!? So I have been debating the whole reasons I'm marrying the man that I am next month.  Ease opinions!!!
