Calling off the wedding...

Ever since we got engaged back in August, it's been non-stop fussing, nagging, and arguments. If I don't constantly remind him or nag him to do something, it won't get done. Our arguments typically revolve around money issues, his daughter, etc. We both have young daughters from previous relationships, and my fiancé has pretty much raised his by himself for the majority of her life. Her mom is a POS. Anyway, we had yet another argument a few days ago and he told me that he doesn't trust me with his daughter and he hates leaving her with me at times. That really hurt me. No one is ever good enough for his precious daughter. I told him that I would be out of his hair in about a month and have since began looking for my own place. Now, he's acting all nice to me but refuses to apologize or communicate about our issues 🙄 little does he know I'm planning to call off our October wedding. The past few days I've done some investigating and discovered that he's lied to me about various financial things for the past year or so. It just sucks because my daughter has gotten so attached to him and his daughter over the past 3 years 😞 sorry for rambling and being all over the place.
