Would this be odd to you?

So a month ago my fiancé called off our wedding and said we “he loves me but isn’t in love with me”. He was basically trying to run me off out of the house and if I didn’t have two kids I would be out. Well like a week later he was all trying to make it work and then now he’s all overly nice and trying to be like everything. Let me start by saying that’s great but does it strike anyone else odd if someone says all that and then all of a sudden is sweet and loving and everything. I’m trying not to overthink it but it’s just two different degrees of thoughts and feelings. All of a sudden he loves me so much and wants to be together and happy when a month ago I was shit and he wasn’t in love with me.
