she needs to figure out if she loves me like a bf or a brother???

Just give her time to think then you must also ponder. Never talk to her while you are still angry or confused. It's possible that the care and need we feel for one person could be regarded as love.If your gf thinks that what you share together are not did not make her feel that you are regarded as her bf, then maybe its time to let her go. You can also try analyzing her moves and reactions especially if you are getting intimate or if you are showing affection to one another. Is she treating like a brother or as someone special? Try also to investigate further if her reasons are true coz she might only be making stories just to end up the relationship.

I think it depends on what you think.You should be honest and tell your thoughts to her.

Set a side a time to do some deep serious talking with her. A time where there are absolutely no distractions and let her know you need to have her clarify her statement. That you thought that you and her had a relationship. If she thought this way she should not have waited until three months down the road to tell you. She would have known after at least a month. I think it would have been sooner. But giving her the benefit of the doubt a month. It is not right that she has done this after three months. I would make it clear to her that if she wants to take a break to realize that you were not going to be sitting on the side lines and not doing anything. That you would be dating and seeing others. She can not expect you to sit idly by while she decides what her feelings are for you. She should already know what those feelings are.
