I'm so confused

Hi all,
I’m new to the forum and need some advice.
My boyfriend and I have been together for 3 months and live together. Things with us have been great since day 1. Lots of affection both verbally and physically. At the 2 month mark he told me he loved me. His family likes me and asked me what I did to him because he is smiling now and he never used to smile. So long story short things were going great up until about 2 weeks ago. He started acting distant. He comes home from work wants to talk about his day and that’s about it. No more hugging and kissing. Sex is almost non-existent, and when we do have sex he doesn’t get aroused like he should (which has NEVER been a problem) and he has a look of disgust on his face while we are intimate. The only thing that hasn’t changed is when we sleep he has to be holding on/cuddling up to me. I asked him if everything was ok, he asked why I would ask that and I gave him the above reasons. He said he is just tired from work, everything is fine and he is happy. A few days later his ex-girlfriend called his phone and I answered it as he was sleeping. She was mad that I was answering his phone. I was mad that she was calling. When I asked him about this he said, I can’t control who calls me. I spoke with the ex later and she said she was under the impression that he still cared and there was hope of rekindling their relationship. She also just got a job where he works. This got me to wondering and I went into stalker mode(that’s bad, I know).
We met on an online dating site and I went to check to see if his profile was still up and to my surprise it was and it said he was “online now”. When I asked him about this he said him and that guys at work go on there to laugh at all the profiles. Well I didn’t believe that so later that night while he was asleep I looked at his phone and he had been sending messages back and forth with a few girls on the site. A couple he had even given his number to and had been texting them on his phone. Telling them how beautiful they are and what kind of relationship he is looking for. I confronted him about this and he said it is all in fun. I asked him if the roles were reversed if he would think it was all in fun and he said no. He then told me look, “I love you and I want to spend my life with you. I am happy with you. I don’t want anyone else.” I have a feeling he is still texting these two girls from the site as he is very secretive with his phone.
My head is telling me to run, my heart is telling me to stay and my gut is telling me not to make any rash decisions. Does he love me? Is it all fun and games or am I being stupid. If anyone has any advice for me it would be greatly appreciated.

Annie, it's only been three months....you're supposed to be in your honeymoon phase. If there are this many red flags at only three months in, imagine what it's going to look like a year in.

For what it's worth....he's secretive....back online...texting others....doesn't want sex with you. It's blindingly obvious that there are other women in the picture.

You dont even know him. What possessed you to move in with him after 3 months? This is still the getting to know each other stage and a lot of red flags are popping up. This is exactly the reason why you shouldnt make any major commitments until the honeymoon period is well and truly over. And by that I mean no living together, babies or engagements. This guy is a cheat and its time to get out now and dodge a bullet.

And in future dont put your heart on a platter for someone to mess with. Be smarter in future

I didn't really plan on him moving in but we were together constantly so we just moved him in. In the past when I have been cheated on there has been physical evidence and I would be ignored for days on end. The reason I haven't made a decision is because he is with me every night, every weekend we don't spend time apart so I honestly don't believe he has physically cheated on me. I know I am being stupid and I think I just needed someone else to tell me to get out. So thank you for you input.
