idk what to do

Hi guys, just wanna ask is it okay if he's like always really busy with uni stuff and I'm busy with college, we always talk but rarely have any conversations. I mean I'm always the one asking about his welfare and stuff like that and never ask me anything. I mean I could tolerate all this when I'm not on period but I tend to get really sensitive when I'm on period especially when I try to say something and his reply will be like.... So? or sometimes is and?..... I get super upset when he say all this things and he doesn't seem to get it. Plus every time I ask him out he'll say no or I'm lazy. But when he ask me out, when I say I have to check my schedule or no, he'll start saying so you don't wanna go out with me now? Seriously, idk what to do. Someone please help 😞
