Great to hear you liked it. Not much you can do about the cost of learning to fly although some parts of the UK are much cheaper than others. However, once you have your licence, there are many ways of flying for a fraction of the hourly rate that you will pay when training.
If you "go for it" you should have no difficulty in getting your licence this summer. I know the weather is going to perk up soon because Mrs QNH has told me so.
