Is this a red flag?

I met this wonderful guy online and through mutual friends, and have been dating him for almost a month now, we’ve been on 4 dates, not a lot.
Anyways, I am currently travelling the country with my family, and had him message me saying that “he felt hurt, and needed to talk”.
On a side note, i should mention that when I travel, I use tinder to meet local people and ask where the best spots are in town. I don’t use it for dating, but just as a means to connect with people (platonically).

When I asked him what was wrong, he said he noticed I was on tinder the other day. And that he felt hurt. I called him and explained the situation. In which he understood. He also is a bit clingy (when we are together). Is this a red flag?

I haven’t had a guy treat me this well in a long time too by the way.
