Any tips how to express feelings and know what you are feeling? I never really understand what i feel.Since 13 years old of age i haven’t expressed any type of feelings towards my family/Friends or my girlfriend. Ive been with my girl for 4 years and i still haven’t said words “I love you”. Im 20 now and I had multiple girls before her and i never felt any way to other girls apart from quick relationships and sex. But, this girl i feel like i respect her and know i could live my whole life together with her. But i dont know how love supposed to feel like?

Thanks.
