Not cleaning up after themselves
You are not your man’s mom. He is not your baby boy. So quit thinking that you should be his babysitter, housekeeper or maid. You have much more important things to do than cleaning up after another adult. If he is too lazy, then that’s not your problem. Let him stay on his own surrounded with dirty clothes, mess and dust. Let him come back to you when he grows up and learns how to do the simplest tasks around the house.

Untrustworthy
No one needs an untrustworthy partner. Whether you have children or not, you need to have a person you can rely on. If your man does not keep his promises and keeps forgetting the most important things, then there is no future. You can forgive him once or twice, but if he does not change and stays the same, then the only way to resolve this issue is by leaving such an individual. Do not deal with people whom you do not trust.
