Girl I like a lot but..

So there’s a girl I like a lot. She’s constantly on my mind. She lives across from me. Well when day she approached me to hang out. I said sure. Well I sort of went too fast and asked her out on the second day. She said yes, but then about a week later she told me she wasn’t looking to be in relationship and that she should stay single. ( During that time a friend of hers needed help and was in abusive relationship. She moved in with her and thats when she told me this. She said she would still like to hang with me though and continue if it was okay with me. She felt that was best especially since her friend moved in). So I talked to some friends and they told me that she was just asking to slow things down. Spend time with her... i also saw this thing that said spending time with a girl will help cause it will allow her to fall for you seeing you as yourself. So I did things were going great. We were having dinner together. She would make me read to her daughter and even started teaching her daughter my name. I would leave notes telling her that I want to steal her. My friend told me thats a good sign that she wants you to spend time with her daughter. Then this Friday she was packing for a trip. We talked about stuff we wanted to do together when she gets back. I woke up took her to the airport at 3 am she made me give her a hug and said ill see you when i get back. She told me to give her my snapchat and she would send me pics. I also had given her money to buy food at the airport and said this is what my family does. She smiled and said im family huh? After she left i sent her my snap and then later told her i hope she made it safely. I got no response at all.... which crazy cause we flirted a lot before she left... :( i have no doubt she likes me a lot. I just dont know what to do.... i dont think ive lost her yet...
