Hey there, So fairly new here, and slightly younger than the majority, but here's my question

I've never had a huge amount of luck with girls, however my one shining quality is that I care a lot about any girl I'm with. It's very possible I could be wrong, but after reading /r/seduction for awhile, it seems in order to be Alpha, I would have to do away with that quality. Is this true? Also is there any way I could balance out the Alpha with the Nice guy?
