Do what makes you happy man, "HAPPINESS ISNT A PLACE ITS A DIRECTION" so instant dont lead yourself to somewhere you think is going to make you happy but life isnt perfect so you know. you just have to let time take it's roll. but seriously if you think you and your girl are going to split up then do it soon if you dont want that to happen then prove something and make it worth the relationship, its the HERE & NOW that counts. not whats BEFORE & LATER well good luck man hope i helped you out on what i had to say about that and maybe so im younger but who cares knowledge is respect
