I realized that I'm getting overly invested into the girl I'm dating. We are both travelling with our family so it always takes some hours to reply. But I realized I'm too weak to wait for her short responses all day so I told her we shouldn't talk for some days. (I don't want to be a texting buddy, but I guess in a kind-of-relationship we need to text from time to time) Obviously she is pissed why I don't want to talk to her and I feel like if I keep acting so needy towards her this will end soon.

I'm trying to keep myself busy but always when I think of her having fun and about her not giving me a lot of her attention I become depressed. (I unfortunately think that I want to possess and validate myself through her) I don't care if she cheats or not so I'm confused and really worried about my feelings.

Is there a solution rather than not texting-at-all or "needy-waiting-for-response" texting?

I know I sound immature and tbh I feel like that now :/
