Not sure what to think but I’m still so sad

So about 2 weeks ago my husband and I decided to end our marriage, it was super tough for me and I’m still kinda going through it. I’m currently pregnant with his baby so we have to keep in contact anyways. we haven’t really talked much unless it was about the baby, well today he reached out to me and wished me a happy thanksgiving, I figured that’s all it was going to be was that but he ended up replying and starting a conversation and for once the conversation was such a good conversation. I don’t know if it was just him being nice or if he misses me in any way. Things are so hard and I have such an attachment towards him. I really want things to work out but I’m playing it cool for now and taking things day by day.
