My (31M) GF (27F) treats me a lot worse than she did with her exe

I know this title sounds jealous as hell, I am 31 she is 27, we been dating more than a year now, Look i love taking care of her, Taking her out and hearing her whining around her annoying boss for an hour sure, But i am not getting the same treatment, She rarely plans dates , She calls me every day but if i am tired or has nothing to say she just goes silent, even her texting seems like reporting, Like i got there i am going to X etc.

The thing is i Kinda knows her ex he works with a friend of mine , He is not a bad guy i think but he gets angry easily, yells and raises his voice and she said that is why she left him, but I know that she used to plan dates and be more attentive with her ex, She even setup his birthday at his office when they were dating, my friend told me so.

The big one was 2 weeks ago, her cousin's wedding and she did not even ask me to come with her, ,She Had a plus 1 and she just went alone, And i know she took her ex to a wedding before, I asked her about the wedding, That i got annoyed that she did not even ask, She said sorry, but she thought the wedding would be old people and family and children and i'd be bored there.

should i talk to her again, my friend thinks so, but it just feels weird saying "hey i'd like you to care for me," seems like begging, like a given in a relationship? I just do not understand, She was the one who asked me out, a whole year and a half after they broke up, so i figured i wont be the rebound guy, I feel like she maybe taking me for granted or kinda like yeah where is he gonna go? attitude?

TLDR:My gf is not attentive to me at all despite her being much more proactive with her ex, is that reason to break up?
