Relationship falling apart with video gaming fiancé

Ebony

In the beginning of our relationship my fiancé did not play video games while I was over when I moved in he played but Always went to bed with me-and he made sure he spent quality time with me first, in the middle of our relationship we even had a deal that we wouldn’t have any phones out after 11pm so we can use that time to watch tv and spend time together our Recently he’s been Gaming 24/7 like every chance he gets I ask him to spend time with me and he always gives me this guilt trip about the game or says one more match or asks to reschedule. And when I try to talk to him he ignores me or I’ll have to wait until his match is over (yes I know you can’t pause a game yes he can mute his mic) and I feel so neglected I don’t even know if I want to get married anymore I talked to him about it multiple times before and he said he’ll fix it and he never does he just says “sorry and I’ll try harder” ..last night it all built up and I broke down and mentioned (since I take medicine that makes me fall asleep at 10:30ish) if he plays all day long maybe he can go to bed with me at a decent hour at least and he told me maybe he’ll lay with me till I fall asleep but If I’m giving him a bedtime he’s going to break up with me because he’s a grown man and this isn’t going to work if I give him a bedtime he also said it’s stupid that I feel like I’m in competition with his game because it’s an object He also thinks If I love him I won’t complain about it.. but I honestly feel tricked or mislead he said he didn’t play in the beginning of our relationship because he didn’t want me to judge him and I probably wouldn’t have been with him but honestly I think if I knew it was this excessive I wouldn’t have been with him now we’re 2 years with 3 kids (2 from a previous relationship of mine) and 1 4 month old of our own.. but I don’t want to live like this (Yess I have my own hobbies but I have 0 family up here I moved to a new city to be with him and yes his sister comes over sometimes but I’m a SAHM still because I just had our baby and I’m dealing with a few medical issues still) but I’m tired of being put last and our relationship not prioritized. Am I wrong if I throw away our whole relationship for my happiness. Do I believe him and stay and just hope one day it will change? What do I do..
