She just seems to be colder to me since I pulled back.

Ummm ... not to me. It seems to me that you haven't really pulled back very much. Asking her about a hickey is not acting "as if" -- it's a challenging and pressuring question. And why were you texting her about the pics and about where she is today? The number 1 rule of DB'ing is to STOP PURSUING. Stop contacting her about stuff unless you absolutely have to talk to her about finances or the kids. What's off is that she feels uncomfortable around the pressure you're putting on her to come back. DO NOT demand a sit-down discussion and DO NOT tell her she can talk to you (which will be perceived as needy no matter how you say it) ... leave her alone!
