My bestfriend has nothing to do with me since I have had my daughter and I can’t seem to get over it?

For context…we were best friends for over 20 years. She acted like was excited about me having a baby and now she is completely MIA. I stopped reaching out and she never reaches out to me and asks me anything regarding my daughter. For the first time in 4 months she reached out to me the other day and asked me how I was. Me being a fool I’m like ok cool everything is fine she reached out finally so everything will go back to how it used to be. I give her some life updates a little bit and mentioned how me and my spouse just bought an Rv. She really doesn’t say anything to me about any of the things I had just mentioned but asks “how much did you pay for the RV”. So I told her and sent her some pictures. Never heard from her again. Like she’s just so weird anymore and I just can’t seem to let it go. Like WHY? I feel like I need closure and that sounds so weird but I’m just so frustrated.
