<human>: Can you succinctly summarize the text in 1-3 sentences?

Me and my girlfriend were 5 years together and after 3 nerve wrecking years (i do everything for my little boy) complaining everyday 'without her changing her mentality' about that she never cleaned the house,left diapers for weeks on the ground,almost let my son ran into a busy road(i was just in time to stop him)and after saying that my 5 year old cousin should of watched him instead of herself,in 3 years never cleaned his bedroom,was to lazy to get her drivers license because she said she didnt have to because i always bring him to school,went for a 2 day vacation (even though i said not to take him also) with my son knowing he had 39 degrees fever and was just 1 week out of the hospital because of a lungdisease(rsv virus) whilst it was -3 degrees and so on....
