I think my boyfreind is being unfaithful.

So I was going through my boo's phone ryt and I happened to stumble upon his text messages and I got curious. (pls guys dnt insult me for going through his phone..im a woman!..its normal.) Anyways I saw a text messg he sent to two different girls by the names of Kiara and Antaya who both work at bojangles with him, talking about how their lips are beautiful and he wud like to kiss them. So I was pretty shocked but not too shocked because I have been suspecting him for sometime nw. I knw I was wrong to do that but common I love the dude and I want to be sure im the only girl in his life. But unfortunately im not. I was pretty hurt and till now I have not told him that I saw the text messages or asked him about them. Im the kind of girl that likes to carryout my investigations before jumping into conclusions and confronting the issue. But I know what I read in that text. If I had my car I wud jus like to surprise him at work or at home and hope his alone. But my car is totaled due to the accident I had on the 1st of this month. So my movement is quite limited. I dont know how to go about this issue guys. I need advice. I care about him..asides the fact that his cheating on me, he really is caring and loving and takes care of me well. But im soo hurt and dont know what to do. Pls advice. No insults please.
