Why is life so cruel

I recently broke up with my bf. He was cheating on me and i caught him. I feel so used and hurt. But i miss the sex so much and the company. We had so many plans and now i am back to square one. Like i want a baby but like i amnt with anyone now. I see all my friends moving into apartments and having children. Dont get me wrong i am happy for them. But i am slightly envious cause i want it to be me. Any guy i meet treats me bad so thinking of giving up men. What do ye think ? Am i right or wrong to think like this ??😮😮😮
