Is my (30M) girlfriend (29F) too emotionally dependent / codependent?

Reddit, I really need your perspective on this.

My girlfriend and I have been dating for about a year. We live separately and usually hang out on our days off (Friday evening, Saturday and Sunday). Sometimes I will invite her over on a weekday to have dinner and spend the evening together. It is pretty rare but she will sometimes invite me to do the same.

Here's the story: The past weekend, we spent Friday evening together, all of Saturday and Sunday together, and all of Monday together too (we both have semi-WFH jobs, I worked at her place then we spent the evening together). Tuesday and Wednesday I didn't see her, but we stay connected by texting.

Thursday evening, I was playing a video game and did not text her for only 2 hours. She claimed I went "MIA" on her and didn't text her all day, which did not make sense to me since we were messaging throughout the day. She said she was really hurt because I didn't make any plans with her (even though we just spent all of Monday together and had plans to hang out on Friday/weekend), and I didn't text her that I miss her (it's been less than 3 days - is that really realistic?). This has really upset her, and though I acknowledged what she was feeling, apologized and explained my perspective, she was so upset she couldn't sleep.

I am worried that there are some unhealthy dynamics in our relationship. Would you consider this too emotionally dependent / codependent? Should we involve a therapist? I just want both of us to be as emotionally healthy as possible.
