Agree with pp about the messaging.
Tbh even a few every day might get on my tits though xD Like, why do we need to message at all if we see eachother twice or more per week already? ...what's so necessary for me to see now via text that you couldn't just talk to me about in 2 days or something? Unless it's a really relevant, funny meme here and there or, to reschedule/plan something for our next date...I don't care. Certainly fuck off with 'good morning' texts. Like, right off. I find all that nonsense far too needy.
But some people love texting.
Either way, be aware of somebody wanting you glued to your phone though. Thats never a good sign.
Nor is them suddenly needing your attention or creating some drama when they know you are busy or have to concentrate on something important. Eg: you're studying for a test or your family are there for a rare visit.
Things like often asking you to run errands for them or do them favors. Even if its just little things. Because its a power play potentially. They know little inconveniences all add up.
Venting with you about all their life problems (which you may notice, could be easily solved if they made different life choices...but for some reason they seem to enjoy wallowing). Always bringing the topic back to their life and what's going on in it.
Seeming to expect special treatment and, being unable to apologise for their wrongdoings may also tie in with the neediness.
