Dating a Liar

Hi everyone, I am new here to the group and wanted to get some advice from people I can relate to. I (20M) have been with my bf (19m--we will get to this in a second) for almost three months. When we first met off of tinder (fr), we immediately hit it off. One immediate red flag that I notice about him was that he was extremely cocky about his job and how much money he made. At the time that we met, his tinder profile, facebook, and himself said that he was 20 years old. Fast forward we start dating and then a few weeks ago I found out that basically everything that this man has told me has been a lie. From his age, job, house, past, everything! I somehow convinced myself that maybe he will start being honest but at this point he has caused me to be so insecure about everything and questioning everything. We are in a "long distance relationship" meaning we are 2.5hrs away from eachother and have been with each other every weekend.

Now I've finally started to come to the realization that this is most likely not going to work out in the long run based on the foundation that this relationship was built on because now I am questioning everytime he is off of work and running around his town lol. Based on all of the serious conversations that we have had about this stuff he had sounded serious and adamant about fixing any problems that may arise in our relationship and doesn't want it to end but I just don't know how long I can continue doing this.

Thoughts? Advice? I'm not new to serious relationships however this whole thing has been a complete rollercoaster from the start and not really the good kind lol. tia
