meeting with ex tomorrow

I (21M) am going to meet with my ex (20F) of 1 month in a few days. how do i go about this?

Hey, I could really use some advice about my ex. We were together for about 1.5 years and had some amazing times, but things recently went south. We broke up after a bunch of conflicts, mainly due to her mental health struggles and her lack of communication recently and a few breaches in trust.

We’ve been in touch a bit since then. She mentioned feeling like she “failed” me, which makes me think she still cares, but I’m worried because I noticed she’s been using Tinder, and that freaks me out. We planned to meet this weekend, and I want to approach it with understanding and support. I really want to express how I feel, but I don’t want to overwhelm her. This is something that can totally be fixed

So, what do you think I should do? How can I express my feelings without making her feel pressured? If she seems hesitant or cold, what’s the best way to encourage her to open up?

I’ve been working on myself during this time, and I want to show her that. Any tips on how to convey that without sounding fake would be awesome.

Thanks guys
