Toddler mad?

So, my son is going to be 2 in less than 2 months. For most of that time since he was born I was a SAHM. However circumstances have made it to where I have to do something to earn extra income. I started doing doordash , and I would go from early noon , maybe earlier, till about 3 when my son wakes up from his nap, then leave again around 4-5 until past his bedtime. It's always been me and him, and we had a close bond, don't get me wrong he had one with his dad, but he was definitely a momma's boy, however I want to say close around the time I started working we noticed he's been acting funny around me. Like I've upset him. He doesn't want to come to me, he's completely attached to his dad. He gets so upset when he leaves to work but acts like I'm a stranger...and while I know it's nothing personal it hurts my heart because I'm used to one way and now I feel like he hates me. He doesn't show alot of love towards me anymore....when he wakes up from naps and sees me he shakes his head and wants daddy...his dad will say " do you wanna give momma a kiss " and he'll shake his head no, or he'll try to pass him to me if he's holding him and he grips to his dad like his life depends on it.He used to only want me to put him down for naps and bedtime now...not so much......so I stopped going out most of the day, his father will go out from morning till afternoon, and then I'll go out around dinner until 11 or so just to kinda of see if I can get that bond back and get some time with him again. I thought maybe he was mad at me for suddenly always being gone....but that didn't work. If he's with JUST me, I get a little more love and affection from him, he'll say momma , etc but once his dad is home it's like Im the crypt keeper. I'm worried about this...he's my first and only child...so I'm unsure of alot of things....I came here for advice and insight...so I welcome everything and anything lol...thanks! No
