Do I have the right to be mad?

I've been giving my boyfriend all my time, and money, just because I care, and he doesn't appreciate it at all. We've only been going out for 3 months. In the beginning of the relationship, he would ask me for extra money so he can buy something, or if I'm at lunch he'll text me asking to get something because he's hungry. I'd happily give it to him, but I never really asked him for anything. Then his birthday came, which made it 2 months of us going out, and I got him a necklace with his favorite basketball team. It was in person, and he didn't even thank me or hug me or anything, he just said stuff like "this is awesome!" or "this is the best present I've probably ever gotten!" I told him his other gift was in the mail and coming soon, and he said "oh okay, well when it arrives, give it to me because I want it and can't wait to see it (it was a DVD of his favorite show)".

This upset me and made me even reconsider getting him a christmas present, but I did anyways. But not only did this boy not get me a gift, when I told him I had a gift for him (a CD of his favorite artist) and what it was, he said "omg yess you got me somethin? Okay well the next time we see each other, give it to me. "

Today, we got into some small quarrel, because he mentioned the CD again. He said "i'm trying to hurry up and get that cd. as soon as I get it, i'm going to snatch it and listen to _____" . I didn't bring up saying thank you or anything, but something escalated out of that, and I haven't talked to him ever since.

I don't know, there's other problems going on with the relationship, but he can be sooo disrespectful at times, and sometimes it just feels like I'm trying too hard and he doesn't appreciate it. What should I do?Do I have the right to be mad?
Sounds like you need to stop doing and giving so much to him and when you stop that you will see how he act and if he really appreciates you and likes you for you. Sounds to me as if he is using you. I'd say leave him alone and find someone who will appreciate you and has their own money.

Wish you the best of luck !
Why in the world would you want to date someone that cannot buy you something. It is not your job or place in this world to support someone like this. Get out while you can.Do I have the right to be mad?
sort of. take a chill pill
he sooo taking advantage of u...Do I have the right to be mad?
you seem like a sweet girl and he might be taking advantage of you or using you and he definetly doesnt respect you. dump him. hes an as(s). or your not telling us if your being really clingy or if hes trying to act cool for you. who knows..
You seem very young.
You do not start giving money or buying stuff for a guy. You are encouraging him to take advantage of you. If he was a gentleman, he would be buying if the two of you went out to lunch.

You are making a big mistake.

Now that you told him that you got him the cd, it would be wrong not to give it to him. From that point on, give him nothing. If he really likes you, he will stick around. If he leaves, you will know that he was just using you.

If he is not appreciative, that is a sure sign he is not a gentleman.

Another thing, if you give, do not expect anything in return except a "Thank You". You cannot expect him to give you a gift in return.

EDIT/
Giving stuff is a way of controlling someone. You are making him feel obligated to you. That is being clingy without smothering him.
I am so sorry to say this but he is USING You! All he wants from you is money and whatever else he can get! He is so selfish too! You need to move on from this guy! You'll see how fast he finds another girl to mooch off of! Please learn a lesson from this. If a guy doesn't respect you. He is sooo not worth it! You will have no problem with getting a guy who really respects you. Please don't allow this to happen again. You let him use you and that's not good for your reputation

You'll have all the moochers knocking at your door

Best wishes and good luck to you!
