Should I confront my boyfriend

Me & my boyfriend are a very happy couple but sometimes I'm skeptical of him because of past problems. He's never cheated on me (as far as I know ) but we have gotten into fights about some of his text messages and his friends who are women . He came home drunk tonight and went out the night before so this is 2 days in a row I decided to look thru his phone since I knew he would be passed out . He always deletes everything out his text messages majority of the time but his FB has a few messages asking girls if they are in our city & should " link up" should I confont him or let it pass .... The messages are from yesterday 😕
