So while talking today, my GF told me that his ex ex boyfriend had recently been contacting her, and asked her to get back together yesterday. While my GF only told me that he wanted to get back together, she didn't tell me what her reply was, and when i asked the first time she didn't say anything. Thinking that she didn't hear me, i asked again, and she said she told him no. So i didn't think much. But remembering that yesterday and the day before she was acting weird when i was msging her, she acted really cold and not wanting to talk, but it suddenly got better today. Am i thinking too much?
