**i know that is their realtionship and her decision and its not easy to get divorced**

**disclaimer:** english is not my native language

my mom diagnosed with cancer 3 months ago as soon it was found out, my dad decided he's "tired" from her and start to cheat on her and being asshole(its even nice to say this to him) by ignoring her and her condition . he didn't even flinch to help her with the all process of her diagnosing and treatment (even didn't take her to the doctors/treatments).in that time i caught him few times on tinder and other dating apps , i didn't knew what to do back then and went my older sister and tolled her about it and she talk to him which helped and he started to change (at time she was after the operation to remove the tumor) BUT after she backed to work he started to behave again and it was seems to me specious so i told my sister again and she said no chance i swore him

fast forward to the last month: my mom find out when she going through his phone that he kept cheating when they been "ok"(after the surgery) and she lost it on him and he even told her he is "tired" from her.

she already filed divorce request

it seems she's lingering on that thought

the reason i say it it becuse she said this is her chance out of this unwanted marriage (long story) and i will be pissed if she will staying with him after that and have to live with the guilt and the untrusful piece of shit

regardles to that i going to cut any communication with him ASAP

I be pissing if my mom wont divorce my dad after what he did to her
