When a girl says she wants space, she means she wants dick and I can guarantee she doesn't want yours. The only way to get her back is to officially break off all contact with her, do not be friends with her, wish her all the best for the future and start banging other girls. She currently thinks you are a loser who couldn't score another chick if your life depended on it. It's not cheating because she's your ex. Prove her wrong. Don't say you're going to get sex with other girls; let her "find out" via friends etc. Do not cave to her pressure. Only agree to see her again if the relationship is exactly how YOU want it.

She "doesn't feel wanted" means you were too clingy, too needy and you wanted her too much. She wants attention, just not from you because you are such a pushover, way too easy. She didn't have to work for your attention. You weren't challenging enough. You didn't say "no" often enough. You didn't pin her down and fuck her hard enough nor often enough. You became more addicted to snuggling with her and being affectionate, instead of making the effort to keep sex the priority and interesting enough for her to keep coming back for more.

Be a man and don't rely on affection from women to have confidence and self esteem, it should come from within, whether you have a girl or not.

Ah the "I need space" in a relationship from the gf. Why are these so difficult for us men.

When a woman wants space it is because she is not getting something in the relationship that she wants or she is trying to make a bigger decision on something else(examples: getting married, moving in together, or breaking up) You have to remain strong an confident here. Give her the space she wants. If yall have volleyball practice together, have fun and dont approach her, let her come to you if she wants to chat. Only talk to her when she initiates with you first. Once she decides what she wants to discuss with you, then she will come to you and talk. Yes, she might and probably will talk to her guys, but you have to be confident and believe that she is yours until she says she doesnt want this relationship anymore. And when she texted you asking "if you are ok". You should have replied with "im doing great", and feed her some BS bout some fun you had during the day or something fun you are bout to go do.

I would give her 2 weeks of space max before you talk to her about where the relationship is going unless she comes to you before that. You should going out and hang out with friends and chat other women in the meantime, dont hookup during this break just chat and have some rapport with other chicks, just to have something to fall back on if the relationship does end.
