In a committed relationship but wants to go online to look for someone to talk to is that wrong?

Sorry this is long So I have been with my boyfriend for almost three years now we live together and everything is great! Yes we have our ups and downs but as of now we are going strong and talking about getting engaged for Christmas and married within the next year :) so we met online on plenty of fish a free site for meeting people to date or friends or whatever. Anyway lately I have just felt really lonely we both have been working a lot and don't see each other and It feels like I'm losing a lot of friends lately friends that I thought were close but don't want to take time to reply to a text or call for lunch! Anyway the few friends I do have I don't get to talk to much and is it wrong of me to go online to talk to people to meet new people? I love my boyfriend and I'm not tempted by other men I have never cheated and he hasn't and I can't imagine my life without him he has been there to take care of me in the hardest time of my life but I'm so lonely I just want to talk to people is it wrong to look for that online? I won't do it if my boyfriend doesn't want me too tho so idk??
