I would definitely get a pregnancy test and just make sure that everything is okay in that department before moving forward, but I would definitely recommend some space- not talking to him or anybody else and just asking yourself what you want, and what you are looking for, and if you miss him because you are lonely or if you really care for him and are willing to work to be in a committed relationship with him. Then, I would recommend talking with him and hearing his thoughts. Because if you're saying youre depressed and upset, it seems like an emotional roller coaster and that isn't healthy. So just be careful, and figure out what it is you're looking for first.
