Advice Ladies!!!

Okay ladies so I need some relationship advice. I’ve semi recently ended an 1 year relationship with an guy. I ended it because he has some attitude problems and he’s and super honest person where what come up come out. He also has an bad mouth at times, he says slick stuff. Me personally got very aggravated and annoyed by this not only that he’s never been around a girl with kids and I have a toddler. It took a very long time almost half way into the year for him to really warm up to her which also annoyed me. Another problem was his 3rd leg 😬 it’s not as big so sex wasn’t as great. Now despite all of those cons he has pros like , he pays the bills, he love to take me on trips buy anything I want, we had got our first apartment together, he’s been very supportive with all my phases of depression, there’s nothing he wouldn’t do for me. He was extremely loyal and faithful, he showed me so much affection. Now my question is am I tripping? Part of me feels like I wasn’t as patient with him while he was learning because he indeed started changing some things but I had already made up my mind to cut it off. Even now he still tries his very best to try to get back with me and says he wants to marry me and want us to be together but I just saying no you know because of the qualities that I want 100% aren’t there but the love is definitely there. Am I being selfish??? Should I have been patient with him? After all no one is perfect!
