My girlfriend have someone else. But she can forgot her love easily. Can I trust her? She say she love me. She caring about me. She willing to do everything for me. Can I trust her?

I'm confused. What has she done that makes you mistrust her?
Are you saying that she cheated on you?

Unless she's done something deceitful, then I'd trust her.

No you can't trust her if she loves you, but is with someone else, are you crazy or something?

Action speaks louder than words. She's with someone else, and yet she says she loves you and cares for you?! It just doesn't make sense. Believe her actions, not her words.

Should I do that??

She didn't want to give her phone number to me even if we were a couple.. I gave her my phone number but she never sent me a piece of SMS.. she said she has someone else that she really love.. but she says she still can accept me.. should I trust her? I really don't know what to do now.. help me guys..

She ain't your girlfriend because she is with someone else and will no doubt cheat on him, with you, behind his back. NO DOUBT if you allow yourself to get sucked into this BS, then you will foolishly deserve what ever she does to you.

Why would you just fall for crap like that in the name of love, that's plain crazy. Read the rules again, and again until they stick, so you understand what a stupid path your on.

But I really love her my friend.. I can't live without her...

You have been given some wonderful and sound advice by these people. You might want to really read what they have written and see how you can apply it to your situation. They are not going to give you thumbs up that its okay to stay in a relationship with a girl that cheats on you,lies to you, and has so little regard for you won't even give her phone number, but yet you're a couple.
Its hard to move on,but you maybe missing out a real girl who will really want to be with you because you wasting time on this cheater.

If that's the excuse not facing facts and taking the right actions for yourself, then your love is not healthy. There is no excuse to be someone else's willing fool, and that's not love. Its just like a junkie needing his dope. She is an addiction you must overcome so you can be healthy, and find out what a real healthy love can bring to your life. You will never know what real love is until you love yourself enough to do better things for yourself, than be hooked on a female who has someone else and uses you for her own purpose that serves her, and NOT you.

So unless you are happy with sloppy seconds, and leftover crumbs, you better really think about what you can, and cannot do. If you can't live without her, then keep suffering, and wondering, and hoping.

Its up to you.

You got to try to go for No Contact. It will work if u let yourself.

she didn't want to give her phone number to me even if we was a couple.. i gave her my phone number but she never sent me a piece of SMS.. she said she has someone else that she really love.. but she says she still can accept me.. should i trust her?? i really don't know what to do now.. help me guys..

You may think you love her, but from reading your posts, I don't think she sees you as anything more than a friend, if that.

I get the impression you have built up a relationship out of someone trying to let you down as gently as she could. It is pretty telling that she wouldn't give you her number and she hasn't used the one you gave her.

Now, leave her and her boyfriend alone. Stop living in a fantasy and allow yourself to let the fantasy go. Get out and meet new people while you live your own life.

I think maybe I should just leave her...

I though you are right too...
