There are some obstacles in the way that prevent the matter being handled as smoothly as you imagined. Even though you’d like to buy something, far better to wait if you want a favourable outcome..
Similarly the build-up of negative feelings doesn't do you any good either. Furthermore, it's distracting and keeps you from concentrating on really important issues.
Try being a little more restrained, and give others a chance to talk too. In this way, you'll get get to know your partner and your close friends even better.
