Promise Ring 💍

So lately my boyfriend is always bringing up a promise ring. Basically one day he hints that he will get me one & then the next day say he isnt. It kind of hurts my feelings because for that little time I'm so happy & my heart is full of joy and then to hear that I won't be getting one breaks my heart. I don't rush things. I don't expect him to get me a promse ring, I just don't want him to give me mixed feelings about one... does this mean he is unsure of me??? Honestly I'm so hurt at the moment. Because I was just with him and he's been talking about giving me one and then hit me with the 'we should wait' line. Why pump me up? Why make me happy to only bring me down? Like I said I don't expect him to.. but don't say things you don't mean. 😪
