get out of that rut

I've been in a workout rut for a while now. I'm running pretty regularly, but I'm not really increasing my distance. I have been doing some hill work and increasing my intervals when I do them, but I'm still not getting results. I know the problem is lack of strength training, but I'm not sure how to remedy that because of all the changes my life is going through. I don't want to rely on DVDs because that will be challenging to stick with once Sean is gone.

I really want to switch my focus to strength training. I still want to run 2-4 times per week, but make them more focused and intentional. I'm going to be able to use the gym frequently once Sean is gone because of my new work schedule and Shannon being more cooperative in the nursery. I'd like to really see some body changes by the time I go to his graduation. That gives me 8.5 weeks after he leaves.

I do have a couple concerns. 1. I am the type to build muscle quickly. That is mostly a plus, but unlike many women, I can bulk up easily more than I like. I don't want bulk - especially in the legs where I really 'collect' muscle, lol. I just have a stocky body type. 2. I just don't know what to do! I still feel like a workout n00b and I always feel like I'm doing it wrong, you know? I end up quitting in frustration or never starting because I'm intimidated. I need a buddy to help motivate me or someone to guide me.
