Having checked, your 'forever and ever' flowering hydrangea plants are said to bloom on old and new wood, unlike the usual H. macrophylla, which might mean they repeat bloom - but not necessarily in practice, according to some forums on the web. These plants are available in the States, and are just becoming available here - the RHS was selling them, so you need to do an internet search for 'forever and ever' hydrangea for your country.
You haven't said which variety of Hydrangea you have, but you have said its in a pot. In the ground, these plants (where you are, and assuming its Hydrangea macrophylla of some variety), grown in good conditions, would normally start to bloom in June and the flowers will start to fade easily by end of July or now. In a pot, the flowers tend to last a much shorter time. Unfortunately, if you have a small garden, a hydrangea is not a good choice because of their size when planted in the ground, although H. paniculata varieties are certainly worth considering - these can at least be pruned back hard in autumn, unlike macrophylla varieties.
I'd add, though, that even with a forever and ever type, you may not get good growth and repeat flowering if the plant is not in the ground, despite their smaller ultimate size.
