Confusion

Hi guys,I am a 24 years old lady.I have been with my bf for 4 years now,lately I've been feeling bored,more like we are drifting apart,I met him while he was studying but later dropped out due to financial crisis,he lost his mom so he worked as a waiter,I continued with my studies and I'm now working,we've been through a lot together.Now he is studying again,so I sometimes have to help him financially,I think dis is really taking its toll on us as we now have to compromise,we hardly go out,I'm really trying but I just miss being spoiled by a man without me spending any of my money..that's where my problem starts,I've met dis guy at work,he was honest he's engaged from da word go,we are now dating but I really feel bad because my bf really loves me and I don't want to lose him at da sametime I think I've fallen deeply for da other guy too,he just makes me feel good about myself,treats me well...we haven't been intimate with him as I'm nervous since I've never been with any other guy sexually except for my bf...I'm really confused,I hate myself for this,it would really destroy us but I'm stuck...plz help!
