Going on a weekend vacation without my little one?

Ok so before I was even pregnant I wanted to take a vacation desperately but never gotten then chance to because I was working full time and had a second part time job. My baby is now 1.5 years old and I’ve been desperately wanting to take a vacation with two of my cousins for a weekend leaving on a Friday evening and coming back the following Monday, evening. I’ve asked my mom which is the only reliable person to ask to watch my daughter for the time I’d be away IF I do go but she kept telling me that if I really think my daughter will stay that long without me as I’m her primary parent. I AM planning a vacation with my daughter and I after I just need a quick getaway with people my age which will also be cheaper for me. I just don’t think my mom wants to watch my daughter because she thinks she will cry the whole time I’m away..should I just forget about the trip without her and wait until she’s older? Her father is pretty much not in her life he comes a couple of times a month to see her for a couple of hours and he’s gonna have a problem with me also leaving her and going on a vacation even though he’s hypocritical and leaving her for them to watch her. Of course I feel bad leaving her but I feel like being away for a little, like I’m literally just working and take care of her which I love her and love being her mom but maybe this is all just wishful thinking since no one is willing to watch her without it being an argument about me wanting to leave her with them for a few days and making me feel like a horrible mom/person...my mom won’t tell me she doesn’t want to deal with watching her but she’ll say something more like if I really think she’s gonna stay that long without me... also her father and his family are not in her life. Her dad comes and see her for a couple of hours a day whenever he feels like it and his family just never cared since I was pregnant so there’s that...
