Yeah.
Blimey, sounds to me the only person you love is yourself and the fun you want.
Do the new mum, your manager, your current boyfriend and your ex a big favor and stop using them all for your own gratification and just get out there and sow your wild oats and be done with it.
You are using an awful lot of people and abusing their right to be treated with a bit of respect just because you want to be sexually satisfied????
You obviously have no idea what real love is.
If you really loved your ex you wouldnt be screwing around with other men, let alone someone who's soon to be a new dad. Good grief, dont you have any scruples?
