Search Results: finding a date with online dating

So I'm a single mother of 1 and he's a single father of 3. We are both very shy but I've gotten to a point that I can be more bold when needed. We started talking on an online dating site and have exchanged numbers etc. So for my first question: he's seemed very interested and had said things like he's so excited to meet and can't get me out of his head but now only occasionally can I get a real conversation going. We do talk every day and when he doesn't here from me he does at least send a "how are you beautiful?" text but does this lack of actual conversations seem like he's losing interest or maybe busy or shy? Second question: he asked me out on a date for last weekend (which I suggested coffee instead because of our busy schedules/babysitters so close to Christmas) to which he was excited about but then family came to town unexpectedly. I then asked him if he wanted to reschedule (date or coffee) for this weekend and he said yes but since then he kind of clammed up and it's now Friday night and he hasn't mentioned our "date" again. Is he maybe nervous to bring it up? Does it seem like he's just not that interested anymore? This is my first time using a dating site and I also haven't dated much so last question : am I just over thinking things or finding things to be worried over? Lol obviously I need some objective advice please!

Is online dating websites my only hope at finding love? I don't even have time for that.
I'm surrounded by couples my age and I feel so alone?
I'm in the prime of my life and I just want to fall in love but it doesn't happen for everyone... Am I one of the unfortunate ones?
As a 28 year old single woman have I missed out on love?
I'm studying at the moment to be a nurse and I work weekends so I don't have a chance to date. By the time I have a job and time to date I will be about to turn 30, which is a ridiculous age to be single!
I'm trying to get my career sorted when I should be getting pregnant (biological clock is ticking).
Am I too old to find love, get married and have biological babies? Should I just settle for the next guy who comes along?
My ex just got engaged and I feel so alone.
I'm at uni and I can't afford to get my eggs frozen. All my friends are married or getting married.
I feel sad. At 28 is a woman still attractive and sexually desirable? Am I too old to find someone and start a family with him?

All my friends my age are married and having kids.

I'm so sick of being single, my heart aches and I'm so lonely.

I want a family of my own some day but I can't see that happening at this rate. I study full time and work weekends.
And all the good guys I know are taken now. Unless they become single then I will remain alone.

I'm trying online dating but it's not really going anywhere
