My MIL plays bridge and learned it from her mother and grandmother. She tried to teach me once and I was completely confused and, frankly, disinterested, so I shrugged my shoulders and said "not for me." I didn't find it fun at all. I found it a chore, and I do like a challenge, if it interests me.
My MIL likes to say that only SMART people play bridge -- but you must understand that my MIL is judgemental and likes to prejudge people on very little irrevelant information. For example, if you don't like bridge it MUST be because you are stupid, because SMART people understand it and like it. My MILs words, not mine, because I am not stupid, nor are you.
I say, if you like it, keep at it. If you are not enjoying it, let it go with no worries. I know my MIL plays with a bridge group, so if you like it and want to continue to learn, maybe join something like that. Or there must be some on-line gaming web site for bridge that you can practice with until you build up your skill enough to at least be able to understand and work with the other players. Have you thought about reading a book on it? That may help too....
