I am fighting with myself to break up with my boyfriend

so a little background i (19F) and my boyfriend (23M) have been together for amost 2 years and for the last 6 months i saw he wasnt putting that much effort into us and I tried to talk to him about it. my boyfriend kind of stonewalled and assumed I was breaking up with him. fought for a weekend about it and finally got through that I wanted change and wasnt breaking up with him. we went to dinner and talked alot and we both understand eachothers commiment levels. i pushed myself away after the big fight and he keeps pressuring me that hes losing me and shuts down. he also has a good chance of going to jail for undisclosed reasons...i do love him so much but I just dont feel as attracted to him anymore but I feel selfish if I was to break up with him...am I? is it normal to feel this way? do I need to talk to a therapist?
