Girlfriend needs a break/time to think it through
Hi all, my girlfriend and I have been together for 6 months, but were arguing rather frequently for maybe the latter 3 months - recently she went for a 3-week long trip overseas and we argued again while she was there.. and when she came back (yesterday) she told me that she needed a break from the relationship (I know this sounds familiar.. ) because we seemed to disagree way too frequently, and she needed time to herself to sort it out... she "didn't know how long she'd take" but she'd "give me an answer" eventually.. I asked "we aren't breaking up right?" and she kept quiet..
I then promised her that I'd give her that time, but sort of broke that promise shortly after when I asked to meet to talk about it. She obviously declined and apologised. Today I sent a cheerful message unrelated to our relationship.. and she didn't reply...
I know I should cease all contact from now on, because the signs indicate that she wants to break up.. yet I am still hoping otherwise because she'd phrased her request this way: "before we go for anymore movies or dinners I have to tell you something".. which sort of suggests we might still go out..
How do I know for sure whether she's seriously giving it thought or has already made up her mind? Any help will be greatly appreciated.
