A somewhat new-ish friend kinda ditched me because she found a bf

So I've known this friend for a year or so but we've only started hanging out more after she came out of a longer-ish toxic relationship. I fully supported her, would listen to her rants and trauma dumps and we started going out more often. A few months later she found a new bf and her messages went from constantly sending me memes, checking on me if I'm not replying (usually due to work), to literally no messages for a week. When I do send her a 'hey what are you up to' she replies after a few days and she's very dry and the answers seem completely shallow, like she isn't talking to someone who she wants to meet up with. In the past she admitted that she did the same for her previous bf and she told me how stupid she felt for ditching all of her friends. Seems like she's doing it again to me now. I know she'd hit me up the same second they break up lol. How do yall deal with these kinds of people?

I am in a long commitment relationship so I am well aware that partners do take a huge chunk of someone's life and I don't expect her to give me tons of attention now that she's in a honeymoon phase but I'd never fully ditch my friends.
