I'm assuming he hasn't always been like this, since you say he's not going the extra mile for you "anymore." That tells me he has entered what I call "lazy boyfriend mode." You've been dating a few months, things are going okay and he's not feeling the need to try that hard anymore. It happens. It usually takes longer than three months, but it happens.
Just talk to him. Women get too hung up on sounding needy. You are needy: you need him to get off his butt and do fun things with you. It's a reasonable request; talk to him about it. Tell him what you need. It's called communication, and it's required for a healthy relationship. Do it with tact and love, and you will very likely get what you need.
Thanks for the question.
Run, It's not going to get any better even if you ask. Do I sound bitter? Hmm, that's because I thought I could talk to my man nicely and explain my needs and he would consider changing. I was wrong.
Pay more attention to yourself for a while. He may start paying more attention to you. I learn that men find women more attractive when they are confident and don't accept their bull. If a man find that he can treat you anyway he likes then he will. They give what you accept. Do actions. They are active beings and words will only make you sound nagging to him. Tell him what you like instead of telling him about his behaviour. All women are 'needy' of love and good treatment. If he cant do those too then leave. I can tell you that since i stop putting up with bull i am more happier and more attractive. I now have men begging me to be their girlfriend. I am now a dream girl all because i am much more CONFIDENT and willing to step away from men who don't treat me right.
