Hello:) Iam not an aries woman (iam a scorpio) however, one of my younger sisters is an aries and her husband is a leo. My sister is also pregnant (about 8 months). Their relationship seemed to start out pretty magical to her, her leo man use to do the most romantic things for her and it kinda swept her off her feet. Of course basing things on just your signs isnt enough sometimes (due to your birth charts or experiences in life etc etc), but il explain their situation with hopes that maybe it could help yours. The thing that kept pushing my sister away was his possesiveness (not saying your this way, but if you are then take note). The key between an aries woman and leo man is balance, both want to win, if both do not get their way at times this causes problems. The leo must allow the aries some control, if not it can push her away. My sisters husband wanted complete control in their relationship, and that just wouldnt go well with my sister. If this is an issue between you two then in order for the relationship to work, the leo must give in sometimes and let her have her way and some freedom. If this does not sound like what has gone on between you and your aries woman, then the next best thing would be too possibly explain why your aries woman left you and then i could be of better help:) Other than that my best advice would be to try and get back what you two had at the beginning of your relationship, pregnancy is never easy, and it makes some woman emotional, me being pregnant makes me crazy lol and i cant think straight, if all else fails try and do as you did to first win her, sweep her off her feet, be romantic. Good luck wish you the best!
