I have been with my girlfriend now for 3 and a half years, our first time out together was actually a trip to Belgium in 6th form. so that was brilliant as we were walking around everywhere talking about everything that was there. when we came back from belgium (we were not going out yet) i asked her if she wanted to come round and chill, that she did, we played on the playstation, had a casual drink then watched a film together. It was brilliant, so relaxing, calm, peaceful and not to mention fun and a major laugh. Best thing that you can do is just have fun man. dont go all out and break the bank, just have some fun, do things that interest the both of you!
