Here's my secret method of communicating via text, email, phonecall etc and not appearing needy.
1. Limit these interactions to the smallest amount of text/conversation necessary. For example, if we are going to see each other in the next few hours, I will send a text to firm up plans and that's it. If it's going to be a couple of days or one of us had a bad day, we actually talk on the phone for a while (it helps that we both HATE talking on the phone).
2. Assume she will get back to me. This might be tough for you. Text her something and then put your phone down. Go take a shower. Walk your dog. Watch something on Netflix.
DON'T LOOK AT YOUR PHONE UNLESS/UNTIL IT MAKES NOISE. Don't get lost in your head and imagine all of the horrible things she's doing instead of texting you back. She's probably taking a nap or a shower or on the phone with her mom. Chill out and wait. I literally go hours, sometimes a whole day
before I get a response and it doesn't bother me a bit. Why? Because I trust her.
3. Take everything at face value unless you have good reason not to. She didn't dump you, she corrected you and there is a difference. Clearly, she values personal interaction with you-this is a good thing. If she says everything is "fine" but acts cold and distant, it's not fine and you have work to do. If she says everything is fine and acts normal, relax and go about your business.
4. Be honest. This one is kind of important so pay attention Jr. I don't know what you're relationship is but if the dynamic supports it, you should tell her (in person) why you feel compelled to text your stream of consciousness to her at every waking moment-unless it's weird or creepy. Explaining yourself, assuming your reasoning makes sense and is valid, might help you get out of the proverbial doghouse. I'd run it by us first. For the record: Because I love you and want you to know what I'm thinking all the time-is not valid and is weird and creepy...just sayin...
5. If you're addicted to texting to the point that you cannot stop, you have one choice. Give your phone to a friend and have them ration it for you. You get one unsolicited text per day, you can reply to anything she sends and they have approval rights over everything you send.
