I think I messed up

Ok, so my ex and I were dating for six months (I’m 29 and she’s 25) and I had never loved anyone like I did her. She said the same and we both we talking about marriage and actually looked at rings. We were with each other all the time basically and were ALWAYS happy. Well, we had one fight this weekend and I said something that hurt her and she just acted cold to me for a couple of days. I apologized several times and she said it was okay, but still acted just cold. When I told her it was bothering me we got into another fight. She finally said “I’m done, I can’t do this, I’m not happy.” So I made the mistake of going to her house and begging for her which as you know just pushed her away and made her so angry.

Now to where I am now. Yesterday morning I started no contact. I texted her and told her I was okay with the breakup and that I hoped she found someone that made her happy. I apologized for begging and the argument and thanked her for all the good times she gave me. So that was it. The rest of the day was very hard but I didn’t text her. I didn’t expect to hear from her at all because of how made she was. I went to bed early and she texted me saying “hope you had a good day” but I didn’t respond. Then about 30 minutes later my phone rings and wakes me up, before I could really think because I was asleep I answered. She was crying and said “Can we just talk?” Well her crying always gets to me and I went with my instincts and told her I loved her. I asked her if she needed me to come there and she said no. Anyway she said she didn’t want to talk about our relationship at all she just wanted to talk to me for a few minutes before bed. (No doubt because she’s so used to doing that.) She started falling asleep and I said if she needed to talk she could me the next morning.

This brings me to today. I know I broke no contact and I guess I should’ve just let the phone ring and then I let her have the upper hand again by letting her know I miss her. Today I haven’t heard from her at all, and I’m trying to stick to no contact. The fact that she called me last night after less than 24 hours gives me hope that no contact will work. I guess I just need some advice on what to do next and curious as to whether you guys think I have hope? Thanks in advance.
