Last year I split from my high school sweetheart. We were together for 18 years from the age of 16. I've been with the same person. I've never looked at another woman but I found out she was cheating on me, again, so I ended it. I love her so much but I have to have more respect for myself then that. I deserve better. When we separated I took on my two children full time (woo single dad lol) but I've been trying this whole online dating thing for over a year now and haven't even had a single reply to any of my messages should i just give up and accept being alone?
