Im confused as well

My gf of 2 years and me split up. I immediately blocked her and went about my life. Not even 2 days later she called. We chatted for a bit and ended the call on good terms. The following morning I woke to a text asking if we could do something Friday and I said yes. Later on in the day she asked if I wanted to come over to eat the rest of the food she got. When I showed up there was barely any food. Witch made me wonder what was her real reason in inviting me. She has also mentioned on both occasions that this doesn't mean move back or anything like that. During dinner she mentioned her oil needs to be changed the plan was to go on a hike Friday witch is today. So last night I came over changed the oil for her we had dinner and I showered off. As I was leaving she made it obvious she wanted me to stay. So I stayed but slept in the other room. Just confused on reading her. She has never been good at expressing her emotions. I know what caused us to split and a big reason I hopped back on to 7cups. 2 years ago before me and the current gf got together. My wife of 5 years left me and took the kids. I was on the brink of suicide. The listeners back then had really helped me overcome that difficult time.
