TS should just dump the gf. Because the gf deserve a better guy. It's not like you are paying everything since you guys are splitting the expenses 50-50. I have an ex bf just like you. He used to tell me that he didn't wanna go anywhere for travel because he wants to save money. After years of breaking up with him, he told his friends that want to go travel to know more girls. Such a contradicting statement. And yah, he is still single. I think he deserve to be alone forever.
