Should i let her go sorry its long but best answer gets 10 points?

so today i was at my friends and ive loved her for about 3 years now well it was great i mean we hung out and she layed her head on my lap and i maged her stomach (shes pregnant it makes me feel closer to the baby) and stroking her hair and just feelin all good about life and such well then some guy comes over and ask for a cup of sugar she like jumped up and walked away i was okay with that so about 3 mins go by and she asks this guy to stay and have a party after that about 3 guys come in im on probabtion and the were doin pot so i hauled *** out of there onto the porch she came out and i asked her to grab my phone she did and i called my ride now im like im leaving so bye and shes didnt say anything so i just left its bein about 7 hours now and she hasnt called to check on me she lives in a ruff neighbor hood so i atleast thought she would be worried but i guess not dont get me wrong normaly people dont mess with me cause im kinda big so i wasnt worried about bein jumped or nothin just wanted her to worry a lil sorry this was so long and thanks for readin my question is should i stop caring about her i mean ive done everything for her i even left my house because my mom called her a and it seems like she dosnt care what should i do
