Why can’t I have one friend????

So a few months ago I lost a friend because his girlfriend didn’t want him talking to other females.

I made a friend in January and made sure he knew I had a boyfriend. He told me he liked me but I couldn’t continue the friendship out of respect for my boyfriend and our relationship.

Made a new friend a few weeks ago and he said he didn’t know what my “motives” were and that it felt wrong talking to me.

I have a good relationship with my boyfriend and I always let any guy I’m friends with know this. I’m tired of not being able to keep friends because of this shit.
