Firstly, well done for doing three months! Honestly, the begining bit can be awful in terms of that tethered feeling and I think everyone here can probably relate to that in some way. Secondly, it sounds like you're not sold on giving up so I would suggest maybe looking at middle ground perhaps? Combi feeding could range from just one bottle of formula a day to formula in the day bf at night even to only giving one bf per day (one mummy I know formula feeds but bf for the early morning feed so she can get a bit longer in bed.) I'm not sure when your summer would be but baby's bf requirements may well have changed by then and if you're out and about, say on your sisters hen do, and start to feel a bit full you can always nip to the loo and hand express enough to feel comfortable. I went on my sisters hen when DD was just over 2 months in the next big city about an hour away and had to do this and then did it again on my work christmas do.
I guess what I'm trying to say is that BF is not an all or nothing situation but also as time passes and baby gets older you won't be tied to your baby as much as you are now so there are options available that can allow you to do the things you want to do for yourself and still keep that BF bond.
Of course if you do want to stop then that's fine too and don't let anyone, yourself included, make you feel guilty about that.
