Better off single?

Is it normal to feel like you are so tired of your significant other that you want to break up with them & be single? I love my man very much but I can’t help but feel like I get tired of him & wish to break up with him because of how he could be.

1) his mother is a psychotic controlling monster & she babies her kids so much that they don’t even know how to do laundry 🙄 she’s already trying to take control on our kids saying she wants to raise them her way & they’re not even here yet.

2) he plays games so much (10+ hours) and so loud that I’ve threatened to turn off the WiFi & stop paying the bill because of it

3) I pay most of everything since I make more & he does help me around the house... I hate the stress I get whenever I have a bad day at work because it’s like if I lose my job then we are both homeless & he doesn’t want to even think about a second job. He’s busy sleeping or playing video games

4) we don’t see eye to eye & he tends to not admit his faults & turns things around on me instead of admitting that he’s wrong.. it makes me think it’s some type of manipulation

Other than that, he’s really a nice guy & loving to his family. Over all he’s a good person but I can’t help but want to just anger upset I want to leave and be by myself and achieve life goals I have for me.. of course me actually doing it I don’t see me really leaving because I love him & I don’t want to be without him..

Is this normal??
