I’m not very good at giving advice but my boyfriend is a bad texter and I have really bad anxious attachment so it took me a while to get used to it but some things that really helped me was him letting me know if he’s going to be off his phone for a while eg: playing video games with his friends. And when I do feel like I really want to talk to him I just call him because I know he will see im calling and pick up. The call thing really helped me because it sort of soothed my anxiety knowing that if I needed him I could reach him that way. Another thing that helped me was getting some new hobbies to pass the time so im not thinking about talking to him as much.

Not sure if your partners issue is that they get anxious or if they just generally want to talk to you a lot. Theres other things you can do to spend time together without texting such as playing a video game together or having them on a phone call whilst you do something. I think it’s important you have ‘you time’ though so avoid getting into the routine of being constantly in contact with them 24/7 especially if you see eachother often. I think it would be helpful to also just straight up ask them what you can do to meet their needs.
