I’m sorry that you feel desperate. Unfortunately, you can’t get a woman who doesn’t want to be gotten — to the extent that she won’t take your calls or return your texts. She’s sending you a very clear message that she’s not interested. Your desperation comes from the fact that you know she’s not interested, you don’t like it one bit, and you want to change things, but deep down, you know you can’t.
My advice to you is to accept the fact that she’s not interested and start looking for a woman who’s actually available and interested in you. Feeling desperate is extremely uncomfortable, and that’s not how you should feel in a healthy relationship.
If you let her go, and start looking for someone who wants to be with you, returns your calls and your texts, then you’re going to stop feeling desperate and start feeling happy.
You didn’t get this girl — but I’m sure the next one will be a better situation! 🙂
