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

A little over a month ago a friend of mine (she is unimportant to the rest of the story) said to me "You're brother asked out Dan today." I didn't really know how to respond, but I wasn't super surprised given my brother (Cole) has had some rough years and being gay might be a reason for being so conflicted over the years. 

About a week later the two of them went on a date to see "The Martian" and out to dinner. In doing so, he told me and my parents that he was going to see a movie and have dinner "with friends." I knew that it was a date because my gf (Ana) is close friends with Dan. 

Fast forward another couple weeks and Cole tells me that he is going to his friends house for the afternoon. No big deal. I hear from Ana that he was actually out with Dan again. My mom also believed that he was at another friend's house. 

Last Tuesday Ana tells me that Cole talked to our parents, and that my dad was cool and supportive, but my mom was a little uncertain. She just told me again today that my mom is becoming more ok with it all. 

Despite what I've heard from my gf who I love and trust, I still have a feeling that he didn't talk to our parents. Especially since he has lied to us all about what he has been doing and the only reason I know the truth is because of Ana. Apparently in one of their dates Cole said that he was cool with people learning about him being gay, but is yet to come out to me while most people in our friend circles know.

At this point, I am confused and lost as to what I should do. Everything I know has come from other people and it is bothering me that he hasn't talked to me. I want to talk to him about it and hear it from him, but I also don't want to force anything on him and make the situation worse. 
   
Thanks for any help.
<bot>: I've learned everything about my brother being gay and going on dates from friends, but he is yet to tell me even though he has told my parents. Looking for help on how/if I should approach him.
