I have lent money to my boyfriend several times while we were dating over the course of 2 years. There are 3 occasions where he explicitly asked for a certain amount and said he would pay me back. I saved the deposit receipts I made to his account as well as emails and text messages where he states he will pay me back. When we recently split up, I asked him to finally pay back the money he owes me and he said he would do so in "a couple of days". However, he keeps coming up with excuses as to why he has yet to pay me. Can I sue for an amount as little as $750?I reside in Los Angeles, CA and he lives in Boston, MA. If I have to travel to Boston for small claims court, can that cost be added in?
