Should I block my ex's number if she continues ghosting me?

I (18M) recently separated from my ex-girlfriend (17F). Our relationship started out strong in July 2025. However, as time went on, cracks developed when we would hang out in public or with her friends because we would have major disagreements with me. Ultimately, she made the decision to break up with me after I texted her trying to check in during November 2025. Of course, I was devastated by this, but I accepted it. Also, if I get too biased or descriptive in this post, I apologize.

For context, here’s a few of the altercations that have happened. I don't explicitly remember when this was, but first, after we finished watching a movie, we entered a Five Below. After wandering around the store for a bit, my ex fished for a bouncy ball in one of those barrels and tried to make it from afar. I tried warning her that she may hit something, but she then says to start being “more fun.” I was sort of offended by this, because I valued common sense in this situation, which never affected my level of fun. I brushed this comment off, though, thinking she may make it. That’s when she completely misses the barrel and knocks some products over. We were equally shocked, but in a good way; we were laughing regardless. My concern, though, was about getting kicked out of the store. Naturally, as funny as it was, I advised her to be more careful in the future. Then I see the smile slowly fade from her face, then it’s gone. Her arms then cross. She walks towards the exit, so I try to ask her what’s wrong, but she never replies, her arms remained crossed. She stayed distant until we rode in her family’s van to a restaurant, saying words to everyone except me.

The second disagreement was when I became her date for a dance in October 2025. The beginning of it was phenomenal, I danced hard to the music and reunited with a lot of familiar faces, which was a night to be alive. She was not dancing as much as I was and didn't talk much, so I went to check in on her every now and then and tried my absolute hardest to make her feel included, but she still stayed silent. Though the dance didn’t end until 10PM, we ended up leaving at 9PM because her shoes were uncomfortable; or at least, that’s what she told me. On the walk out, she told me to stop being so “cringe” and I teased her, because being “cringe” can’t stop me from having a good time.

The third disagreement happened later in the month during a scary attraction. It was full of a bunch of spooky props while volunteers tried to scare any people walking by in a series of labyrinths (haunted houses, cornfields, etc.) that made it hard to notice which direction you’re walking. (Some even had chainsaws!) I, myself, did not get intimidated by most of them, mildly uncomfortable at most because I saw their shadows a bit before they could jump out. However, my ex had a problem with it because she wanted me to show fun from a good scream, claiming her screams were not from fear, rather from excitement. I explained to her afterwards that the experience was fun and exhilarating for my body and I still had a lot of fun with her, but she still complained that I didn’t scream.

We had one final argument during a second prom in November 2025. She was extremely nervous and rarely talked to me during our entire stay there, even avoiding dancing altogether. I tried everything to make her feel at home, but she didn’t get any better, then she told me to give her some space. Without hesitation, I complied and gave her the distance she needed. Then I went to dance and talk to a few friends who I haven’t seen in a while; we really had great conversation. My ex and I ended up leaving early again; I don't really remember the reason why, but maybe it had to be with her stress.

After the breakup, I texted her a month later in December 2025 asking how she was doing, but I never received a response from her, which concerned me a lot, fearing she may have blocked my number. I texted her a second time tonight saying that I was very concerned because she ghosted me, and I just wanted to make sure she was okay. I still care about her even if we’re not together anymore. I know I might sound like an asshole, but if she doesn’t respond to my texts within the next week, I might consider pulling the plug on our friendship altogether, if there even is one left.

If she continues to ghost me, should I cease contact?
