<human>: Give me a shortened version of the text

Alright, so. Where does one begin? Me and my room mate have been friends for a little over a year. We have many differences, but we still end up getting along at the end of the day and I thoroughly enjoy her company. 

She has a boyfriend[24m] who she has been with for a while. Since we are good friends, whenever the two of them fight I am the one who gets called/messaged. I was completely okay with this at the beginning. You can say that I always like being that person but for the past few months it has been more than awful. Now it has become an emotional conflict on me wanting to be a good friend and me being tired of feeling used.

She has told me awful stories about how he hits her, and then the next day brings him to the apartment.
She will then tell me she has cheated on him after a fight they had, and then brings him to the apartment the next day.

The list goes on and on of events when she has come and I have consoled her about them, Everytime advising that she should "look after herself" and "realize how much she is worth." 

The worst part? I don't know if I believe her. She is my friend, but I know how crazy she can be. She always wants to control him, something our whole group of friends knows, and she desperately wants his attention 24/7.
I like her boyfriend, too! As a friend he is great, has picked up meds when he heard I was sick, often picks her up from work, showers her with gifts whenever he can.

Now. I'm all for girl power, and chicks before dicks.
But I'm getting really tired of always worrying to then just feel bad the next day when he's making breakfast for the whole house in our living room. I don't know what I should do.
<bot>: friend claims to be in a toxic relationship, does nothing about it. The boyfriend doesn't seem as bad as she says he is, I sometimes think she's lying about it.
