So I received an apology text from someone I dated a month after we separated. This guy was really sincere and caring but we separated after dating for 4 months because I wasn't ready to commit. He said some hurtful things to me before the relationship ended like I used him and etc.. but one month later he texted me out of the blues apologizing for hurting me and I felt his sincerity in the message. I replied back saying thank you for the apology and I hope he's doing well. But ever since then I never got a response from him. I know I didn’t ask a question but why do u think he messaged me? Does it seem like he still missed me or was it something he wanted to say before moving on?
